[4K] Making an Engine Wiring Harness (89-94 4g63)

- This video is a good start to finish example of what to expect if you're considering starting from scratch on your engine harness. Nobody has this Elantra chassis anymore, but its engine controls, ECU and wiring harness are all from a 1990 DSM, specifically a Plymouth Laser if it matters, and the engine closely resembles a turbocharged 4g63.
My documentation, some of my notes and resources worth sharing, and some free public-facing posts with extra footage are now on my Patreon page. Free. There's other public-facing content there for those who don't know. Whether you're looking for more content, wiring help, or you wish to contribute...

I could have made this about 15 minutes shorter, but felt it was necessary to include my most important mistakes and troubleshooting. It's a more realistic and accurate example this way.
I can't stress enough how you should take notes. Take notes about your notes, take pictures if you can (you have a phone), and pay attention to every detail on this job.
I've done a lot of electrical repairs over the years, enough to understand what I'm doing, and the basics of how to complete a circuit, what things are, and what they do... but I've never attempted a job this big before where my wiring was the actual component itself. IT WAS WORTH IT! So many people talk about needing to do this, but few of them ever take the leap. I know I dreaded it, but just like most other big jobs once finished, you walk away with a wealth of knowledge about your car, and a satisfying dosage of confidence and satisfaction. This is not your "I changed my own oil" level of satisfaction. This is different. It's a whole lot bigger than that.
I have a pretty strong suspicion that there are people out there who would use this as reference material. I'd advise against that unless you want results like mine (which frankly aren't too bad...). If you don't have a '89-'94 DSM, then my reference material won't be very helpful to you because my circuitry isn't like yours. You may notice that I'm using a newer schematic than the harness I'm working on, and this can be problematic. Get the electrical service manual for the specific year or production of car you're working on if it exists, and use that. They're easy to find with any search engine. Or you could check eBay, they get bought and sold all the time. There are also web subscription services like AllData that can help you find the information you need. Don't do this for the first time without the electrical service manual and your detailed notes that you made yourself.
I'm not a professional mechanic or electrician. If you prefer instruction from professionals, I suggest you visit High Performance Academy here on TH-cam. They give a pretty size-able sample of gold away for free, but if you want access to the gold mine, then you have to pay to dig. They're possibly some of the most experienced professional automotive instructors here on TH-cam, having set World Records with a couple of EVOs and customer cars, so they know a thing or two. Their videos play out like classroom instruction with alternating lab days. They do live streamed demonstrations of their lessons on their in-house dyno and hold Q&A's. I've never bought their classes, but if anyone has a problem with what they get here for free, don't downvote, just go there. If you didn't find what you need there for free, then buy their training. I'm nice enough to point you in the right direction. This is my unsolicited endorsement of them. They don't know I'm posting this here, I just care enough that I want YOU to find what you're looking for.
FAIL at 21:26. I was more focused on the shot than on getting the pin in the right hole.
bae: I'm alone. Come over.
me: I can't. I'm watching a man rewiring his car's harness from scratch on youtube.
** me: I can't, there's a lockdown :(
Same here xD
@@proatw that's a lame excuse, better to just be gay
I'm watching a dude on TH-cam rewire the engine on his 1990 Hyundai*
Stings more when you say it like that, underscoring that it's not some prestine muscle car worth houndreds of thousands or something like that :P
There's TH-cam.......and then there's Jafro.
Good to see you here cheers from your faithful subscriber
Dude, you're just as iconic to a lot of us as Jafro.
Two legends of the DIY car community.
The amount of work that went into the production of this video is inspiring
You can only find this characteristic in men.
Jafro, you're the man. Hands down you give lots of energy to cars that I didn't consider cool when coming up in the 90's. I can appreciate the time and effort that went into this.
Caleb, the world needs Built. Hopefully, you can find it in you to come back.
I literally bought 250ft of various colors of wire last night to start this and bam now you post a video! Fuckin prime!!!
How’d it go??
Done yet?
@@samuels.4622 nope never touched it
@@chuckth3clown dude are you me?
@@chuckth3clown lol! Come on, man!
Okay got one for you! In 1980 My brothers father in law, owned an old Auto car Truck. Wiring was bad, was so old was the cloth covered stuff. Well he had a brother that was visiting him. He was a old man, and had a stroke. That left him with difficulty in use of left arm and other things. The man was a very nice and I like him. Now one day the father in law, he put his brother to work replacing the wire in the truck. I asked my brother what was he thinking? My brother said, don't worry about it. He'll get it done and asked me to keep eye on him and get him anything he needs. So I show him where all the wire was and tools etc. Had, like you every color you could think and in different size. So he went to work replacing the wires. I went on with my work in the shop. Every once in awhile I would look out at him. He was working away, had wire all over on the ground. Late that afternoon I walked over to see how he was doing. And could not belive what I saw... He was replacing each wire, one at a time and was doing good, except he replaced every wire with only white wire and same gage! No colored at all. I did not say anything! As I watched, he was talking, telling me how he had to go to school and took a wire class on this new plastic covered wire. How to cut it, splice it, and crimp it etc. He said, When they came out with it and remembered when was all new stuff. I walked away... found my brother and told him what was happening, and what he told me about school and how long he was in class for it! That's when I found out something about not to judge people, See he was a rocket science engineer, and worked during the war and with NASA building rockets before his stroke. I was shocked! Now the truck did run and everything worked when he was done, just was with only one color of wire. All white, one gage!
@Lassi Kinnunen same color?
There was a time we’re wiring wasn’t colored. Check out old Italian autos and such and you’ll see it’s all exactly the same color. I wonder if the same was true for rockets and such as they are kind of single use.
Wires: The movie
Directed by Jafro
Seeing a wire harness done right is a thing of beauty. Most of the time pro mechanics don't even bother using the correct crimping tools or splicing procedures.
About 5 years ago I binged watched your channel on a different youtube account and I was waiting for more videos to come out. Then, I got a new youtube account. Finally, in 2023 youtube algorithm got me back here and I couldn't be happier.
This is....epic, I spent 30 years in the biz as a tech, 20 of those as a Mitsu tech(85-05)....I applaud your tenacity sir!
Doing this for 30 years? Are you overlooking your own tenacity!? Respect!
@@Jafromobile I did many wiring repairs over those years but nothing even close to what you did, heh navigating Hyundai service info can be a "challenge" eh? (Did almost 4 yrs @a Kia dealer)...killer job dude, most I've done is rewiring/upgrading my old 73 Honda cb750 (added relay ckts for ign n headlamps to take the load off the ign switch).
.idk if I would build a harness from scratch like that but...I appreciate seeing you doing it...means we alll can!
Yep!! And, the wire striper tool is pure brilliance. I’ve been scrounging salvage harnesses just to getting the striped wires I need… imagine my storage area
Don't know why this was recommended to me, or even why I clicked on it. But, I watched it all the way thru. Good Video.
Hey we both uploaded DSM content today, DSM content overload for the people!
HECK YEAH! The most consequential imports ever built. I bet all kinds of DSMs are getting fixed right now while everyone's locked down. The only thing that interferes with their maintenance is their owners having a day job.
So I just happened upon this video, but figured I'd pass along some "knowledge" if anyone needed it down the road. There is a place in North Carolina called Miller Import Parts that dismantles DSM's and other cars. Found them when I needed a crossmember for one of my Nissans. Perhaps this will help either or you, or someone else, find parts if they ever need them.
@@TylerGotAYTAccount Ya I friended Stevie a few years back and got some hard to get parts from him, real good dude.
@@TylerGotAYTAccount lol i actually purchased a 1gb engine harness from miller import parts they are great to deal with
I have just finished installing an entire vehicle wiring harness in A 1977 Chevrolet Step Van Ice Cream truck. Mophorn Wiring Harness Kit 12 Circuit Hot Rod Universal Wiring Harness Muscle Car Street Rod XL Wires. It wasn't the exact harness so I had to remove a couple of the Circuits, then I added and electric Radiator Fan and Music Box and Flip out Warning Sign and Front and Rear Flashing Lights. It took me a lot of notes even with the proper Wiring Diagram and a ton of Pictures. It took me a Month of working a few hours everyday, but everything is working like it's suppose to. I had never done a Full Vehicle Wiring Job before, but it came out working so I am Proud of Myself for doing it.
Money! I feel like that's the most appropriate answer... 'cause once it's got all that, it's time to put 'er to work!
Your uploads are nothing short of stellar. You deserve to be in the YT automotive content creator Hall of Fame. Not only are your uploads informative and creative, but entertaining as well. One does not have to be specifically tied to JDM products to follow your work. As someone who has followed-subscribed for quite some time all I can say is thank-you for all the effort you put into all your work . You rock Jafro!
"cut up more than a magazine in jussie smollett's living room" -- remind me not to eat breakfast cereal when watching your channel. You owe me a new keyboard.
I don't understand that reference.. could you please explain?
@@ajgonzalez5109 Racism and homophobia are real societal problems in America, sadly even today. But Jussie... Well, read his Wikipedia article. Or watch Dave Chappelle's stand up routine about it.
@@RyanBissell a simple no would suffice
@@RyanBissell I get it now, it's a joke on forging documents, hence the cutting magazines reference. Thank you for pointing me in the right direction!
@@ajgonzalez5109
No, he sent himself racist anonymous letters serial killer style by cutting out letters from magazines.
I actually enjoy wiring. But this was on a whole new level. That wire marking tool is just genius. Thank you for this video it was truly great
no kidding, i really want one.
That wire striper is incredible.
This going have to be the sweetest 1hr I watch TH-cam, like button hit already.
On a non-daily driver, making a harness is something I would in fact like to do. When one company contracts from another for an engine, electrical information in manuals becomes messy and almost useless. Jump over to a DSM car and a factory DSM manual, and it's utter perfection. There are even patterns for troubleshooting, and even really basic language of what stuff is and why it is used.
Mitsubishi wrote the best service manuals I've ever read. Even with the bad translations they're fantastic.
Worth the wait, for sure. As someone who has completely re-wired my own car, converted from a carb to EFI, converted from mass air to speed density, and completely rewired from fuse box to cigarette lighter, I especially admired your attention to detail. It's a long and tedious job. Props to you for actually using the correct factory wire coloring, my junk is a mass of red and black wires! This is by far the best harness wiring project I've seen on the 'net. I'd love to see a before and after picture of some of your log traces to see the difference in noise in the different channels, especially the TPS, MAP and Battery voltage channels. I know my own logs cleaned up quite a bit when I put some attention to the grounds and signal wires. Great job!
That PVC marker holder/striping tool was genius, seriously. I'm a cheap bastard with a Honda, so I usually just get marked wire out of the newest/biggest Honda I can find in the junkyard. I'm also usually only replacing one or two sensors worth of wires that I think need to have the same exact color.
This is probably one of the best cable porn movies:
- Unnessasry chatty parts fastforwarded
- Good quality strippers and properly cut dongles
- Kinky harnesses/whips
- Money shot at 1:17:52
I'll even go out to make this statement if I was ever in a position and I met someone like you I would make sure you had a garage that you'd be able to do anything you wanted in it just for the circumstance that you were able to do a video like this and educate people that's where I think this should go to thank you again
"Its on its sixth build and its third car MEOW"
Made my day! Salute to the Super Troopers.
Alright, I just watched an hour and twenty two minutes of you doing this wiring. On a vehicle I have absolutely no notion of every purchasing. I must say though, for the black wire being the only cause of the issue you had. PHENOMENAL work good sir!
Welcome To The Madness idk why but it’s good entertainment
1:14:00 Stupid black wire looking like the other black wire.
As a automotive electrical engineer I congratulate you on a great job. Really well done.
Some tips from years of experience, None of which directly apply to what you have done, you have a done a great job and will have leant an unfathomable amount about how you vehicles connected that will assist you greatly, anyhow:
- Cheap/off brand ratcheting crimp tools will let you down more than sturdy conventional crimping tools as they lack the "feel" that you get with conventional crimping tools when setting a good crimp force, Thus they tend to produce a lot more under crimped terminals when using wire sizes that don't fully fill the barrel of the crimp.
- Fuel and vapor stable Raychem/heatshrink covering in good quality will cost nearly as much taping to assemble for sending the loom away to get covered with braiding $10/foot usd. The general procedure is make the loom but only tape with loops every 6 inches or so, test it in the vehicle then send it away for covering. This is a service performed by loom manufactures OR boat and marine rope manufactures. You can also customize the color of the braid. But to be honest split corrugated sleeving and tape is underrated. It has served the automotive industry for years with its cost effectiveness and serviceability. Even the aerospace industry uses tape and split sleeving.
- If you want to do a one off and don't want to buy 100 rolls of cable you can source 25+ core cable that is all colored, strip the outer off this to get a vast array of colors. Never use numbered cable in an automotive environment unless absolutely necessary as eventually the numbers will come off from brake clean or chaffing.
- heat guns can some times under cook those heat and solder connectors, good brand ones will withstand a high heat without splitting, cheap one won't. Never use those on tarnished wires, instead use the red/blue/yellow crimp terminals that have the glue and shrink (hella 8230s or other brand equivalent). the low melt solder in the solder ones tends to struggle on any wiring that's not 'bright and clean.
- make it on a template board just in case you ever plan on doing it again.
- Every one gets fooled by the same color wires transposed on one off builds, it's a "right of passage" like leaving the retaining ring off when assembling a garden hose fitting.
I recomend 4rcustoms, I get all my gxl wire there, all colors with all stripes!
I'm in the middle of making my harness from scratch for a Mitsubishi pajero with a haltech elite, deutsch bulkhead connectors on the firewall pass thru, deutsch everywhere and module bits of harness.... I literally bought 6000+ feet of wire, fully concentric and braided sleeve covered.... I love doing wiring!
Evil Me seriously! How did he not find them when searching for wire??
Your WIRE STRIPER is genius and yes I searched online...got distracted by all that stripping...then the other half got home and we got distracted...by the stripping...and that's my excuse for taking 18 months to see this to the end.
I know what you mean about DSM wiring. I used to own an old 88 Dodge Conquest TSi widebody and had nothing but wiring issues with that car. Hats off to you sir for going through all this work 👍🏻
i cant belive i watched 1 hour and 40 minutes of wiring and didnt get bored
Thank you, that's an enormous compliment!
Wiring is like porn to me being an automation electronics engineer. Watching it done at this detail and with Jafro's easily comprehending explaination for as long a movie lasts... was the high point of the quarantine!
I just bought a 77 dodge truck and wanted to fix the mess the old owner has...and you answered my hours of searching for colored stripped wires ....thanks
I'm so glad I watched this. To see the Joy at the end when it started was extremely satisfying.
Just pulling the old harness out made my head hurt. By the time he unpacked all the tools, wires, connector etc. I had a migraine! Just got done redoing the harness on my sons 4 wheeler and after I was finished I kicked myself in the ass for not just buying a new one, I couldn't imagine even attempting one of this size. Great video funny as hell and really an awesome job.
I'm about to do it again... That's the other downside. Once you've done it, you're less resistant to starting this job up and doing it again. Seriously, read down your bucket list. You'll find this item re-appears. I don't know why it does that? I thought I was finished?!
@@Jafromobile I agree you do become less resistant. I like to leap into the things I'm not completely comfortable with because of the experience and knowledge I usually gain (after alot of swearing). This however was something I definitely wouldn't want to tackle unless I knew that car inside and out which clearly you do. Great job I look forward to the next one.
20 minutes in and my fingertips, neck, back and eyes already hurt from just watching this. Nope nope nope nope nope nope nope
yes yes yes lol
I already felt dizzy just watching this 🤣
I specifically bought the HP Academy wiring course so I can build a harness one day for my GVR4, but this will be a great, more concise, and more specific reference to compliment it!
GREAT job, James! Those guys really are awesome. I should have done the same, but it's more organic if I just do what I know how to do. It's a respect thing. It would have been really messed up to buy their course and expose any of it, but who am I kidding? I can't do what they do-the way they do it. I might have to make one for my galant as well, we'll see? I hope not.
That Juicy Smolliette joke was on point.
I was just looking at materials to do this job on my modified FC. Came to TH-cam and thought it was making a recommendation based on my searches. Talk about good timing.
I get wiring questions all the time and I've never understood it? I'm like, "haven't you seen the Hyundai?..." Really this video was overdue!
36:05 That poor ladybug is like WTF have I stumbled into????
Wow, you could tell it was a ladybug. OMG, 4K is worth it. What I didn't know about ladybugs until I was making this video is that they eat spiders. I had an outbreak of them in my garage and at first I thought it was a problem. I haven't walked through a spiderweb in my garage now in over 4 months. They're gone. I'm grateful! Those little bastards ate every last one of them.
@@Jafromobile I had no idea. But I do know you can order boxes of live ladybugs on Amazon, so I'm about to and release them in my garage.
@0:30
I've been wanting a harness for my Escort for a few years now. I clicked this video and lucked out it was Jafro. lol.
Amazing! You strongly remind me of This old Tony.
I imagine this is how This Old Tony sounded in 6th grade
This movie has everything, intro, trama, drama, plot and a happy end!! I'll started yesterday a similar project, I see everything is possible.
I have worked on a few of these 1g harnesses, at 11:03 that connector is ether for the water temp switch on the thermostat housing it is for the A/C on a 1g dsm, or it is possibly for the the A/C pressure switch they both use a similar style connector. at 11:14 that round connector is for the A/C clutch 1g dsm. at 12:28 that is the rear defogger relay for a 1g dsm commonly deleted from the engine harness on dsms.
"Just buy a harness, if you can it is cheaper" Naw, now you know everything there is to know about your electrical system, what goes where, why it goes there. This is super valuable info, that can only be understood by making your own harness.
Uploading damn movies now! Nice! Who needs Netflix when we have Jafro?
There is NOTHING more satisfying than finishing an engine loom or doing a full proper repair. Personally I prefer TESA high temp loom tape for the ends and corrugated tubing for the trunks. I heat shrink for abrasion if wires come out of the trunk at any point.... great job
I’m as relieved as you are that your harness worked and going through all the struggles. You’re far more patient than I am. To say that you are a tower of strength and endurance is a massive understatement! Your meticulous and unyielding and that is why your following is so very loyal. Not too many fit in your category because most either don’t care or run out of patience. We are so glad that you don’t! Jafro, you go guy! Looking forward to the next one big time!👍🏻
I might take 1 day off? Maybe I earned it?
Jafro, you could take off a week or whatever time you need. It exhausted me just to watch it. It was easer for me to tear down that reel winder back in 2014. That was a terror, but I remember that wiring harness and all the hell
it gave you! I look forward to that block rebuild after all that he’ll you went through with that. You got through more than anyone else I have ever seen! You inspire people and give hope to others. I’m proud of you and how much patience you have. I’ve been here since the Stone Age and I’ll follow you to the end! I respect you!
It’s the prep work that gets you down the road to becoming your own assembly line.
I apologise now, I couldn’t help but smile when you SIGHED at the beginning, I think we’ve all been there at some point. Great content as ever, prefect isolation entertainment.
Ah yes, Jafro. I may not own or plan to own a 4G63 Engine, but the knowledge, foresight, cautionary tales, mistakes, insights, and general information dumping are all welcome. I feel more confident and more knowledgeable in how to go about tackling my projects in intelligent ways. Don't change a thing Jafro. Hope to meet you one day and go for a ride in eachothers projects.
"probably enough to do 3 or 4 cars" good thing you own three or four DSMs
I made my own harness a while back and now I came across this. It's so funny to see someone go through the same issues I did but obviously some things you did were different and it was a relived nightmare watching you. I would think it would be great to sit down or even chat about harness building
Has no one ever thanked you for the time and effort you put in these videos?
Thank you, I appreciate you information you always provide. (:
i gotta say, i clicked on this having absolutely no idea who you or your project was and i feel like we just went on a cross country road trip together. Excellent video. I am blown away with your dedication and expertise. you sir have earned yourself a subscriber!
You are a legend! I love the in depth walk through of the process.. I have always wanted to rewire a entire engine harness but haven't had a chance yet..
I've been working with wiring harness technical drawings and diagrams for the past 12 years. I know how hard a job like this can be. I admire your Work and immense effort. Congratulations.
Marcelo from Brazil
I'm glad you made this video so I didn't have to. The custom wiring I had to do on my Datsun was quite the project. Although there are companies that make custom harnesses and can easily replicate a stock harness, in my case and yours, there are several other circuits eliminated or added that you may not account for when ordering a custom harness. The price is well worth it either way. I wouldn't change the learning experience for anything and the knowledge gained in knowing what and where each circuit is and can fail is invaluable.
Side effects of you new harness may include some changes to your tune since new, less resistant wire may carry a cleaner signal. I'm thinking I'm getting phantom knock due to a cleaner and shorter signal from the knock sensor. When I replaced my chassis harness with TXL wire, I found several circuits to be more sensitive due to 45 year newer and less corroded wiring technology. My engine harness is all Mil-spec tefzel wiring and allowed me to use lighter gauge wiring in many circuits. This was especially useful because, like you, I found that they don't make striped wire in larger gauges.
Maybe some day I'll post a much more condensed version of your video about my own harness powering my 4G63 Datsun 510 #4G63510 :-)
Watched it all, never fast forwarded and so grateful I didn't... Jafro seriously the best.. a true DSM God
I make the videos you have to watch at 1.0 playback speed. I sped it up for you. ;)
@@Jafromobile much appreciated!! Now for that engine build!
Hour and a half of Jafro? I think I can stretch it out for another month or two of quarantine.
Also, caught the predator reference at 1:20. Nice.
Great shout on the predator reference lol. I had skipped that somehow. brilliant!
Ur was the first video that dressed EVERYTHING I needed to know even the pins on and OFF / OUT of the harness !! Thank U , I’m a woman so of course it’s harder for me and I’m in my later 60’s so I still save money on fixing my own
Love it Jaffro! Who needs Tiger King when you have the DSM Wiring King!!
This is by far the biggest behavior modification this car is going to get. I can not wait to see some passes out of the little one now. Great work Jafro
@1:17:51 - damn that's satisfying! lol. Watching this WHOLE video was awesome. Even crazier that you edited ALL of this footage too! MAJOR props to you Jafro for editing this video on top of making the engine harness. Best DSM content on TH-cam! :D
Hi.
I truly appreciate your KISS (keep it simple stupid) approach. If you can build what you need, get exactly what you want, and save money to boot, BUILD IT. Hoorah. I was a master technical instructor in the military and when I tell you your explanations are very good, and the little extras you sneak in are appropriate and appreciated, I think it's an informed opinion. But that's my opinion.
My expertise was in digital equipment technology. I'm 68 and retired now and am trying to learn more about auto maintenance. Thanks for an excellent presentation. I enjoyed it and learned a lot.
-Dave
Boost Circuit??? Did I hear that right??? Are we putting a boost gauge in once again?? God this video was awesome, the only thing I think you should add to every video that you current don't; is the links to where you bought what tool etc. You should get some kick back from that as well. I know a lot of TH-camr's list where they bought they materials in the video description. I will be watching that over and over again to see what I missed the first time. I'd imagine you'll be making a new harness for the Colt as well...Ya know since you have spares :-) Glad to see this video, can't wait to see the next one!!!
The harness is already done on the Colt. That doesn't mean it's any better than the one that used to be on the Hyundai but... Yes. AND. That means it has all the connectors on it already. All of the cars have the connectors. The only bad ECU connectors were on the Hyundai. That means I can break them in half before I need to use the one with a "bad" pin 106. Some people accuse me of being an optimist.
I'm leaving everyone in the dark about the boost circuit. I've got a trick up my sleeve if it works...
I can not convey to you how happy I am for you. Under the best conditions, a Mitsubishi electrical system can be iffy over time. I know how satisfied you are and that your car performance will finally be focused on tuning and upgrades.
P.S. They do not call it "Painless" wiring harness' for nothing. lol Thanks for taking us on the journey. I can see myself doing this in the not to distant future.
"sixth build in it's third car meow"
Did he say meow
Yes he did
I'm sorry meow, but I'm gonna have to give you a ticket!
Do i look like a cat to you?
Am I jumpin' around all nimbly bimbly from tree to tree?
Do you see me eating mice?
I can respect that. I replaced the engine bay harness, dash harness and forward lamp harness on a 1968 gto. I didn't make it. That was part of a restoration.
That is exactly what my face looks like when looking at a wiring diagram
Never had to make a full harness before. I've had to replace a complete harness on a 2018 chevy pickup. That was enough work! Building the harness from scratch... NO WAY. Beautiful work, professional, and a great looking product. I'm guessing you could make some money selling harnesses now.
Saw the title, channel, and length of video. Immediate like before even watching the video. Time to grab the popcorn! I know what I'll be watching for this evening in quarantine.
I did a partial rebuild of the wire harness on my 95 GSX when I transplanted a 6 bolt into it. There were a ton of wires and plugs that I never could figure out what they went to as they were not even on the wire diagrams. I upsized quite a bit of the power wires and made new main power and ground wires out of 0 gauge with crimped solid copper connectors. It took a solid week of work to do that having about quadruple checked it as I had made some mods to add in a 5bar, inlet air temp and EGT sensors. I had a ton of issues with DSMLink but finally got it running on speed density and logging egt and wideband O2.
He saw my comment about last video being literally one minute and was like..i see your comment its length you want.... 90 MINUTES IT IS!!!!!!!
I did... I saw it... I was all like, "be careful what you ask for..." ;)
🤣🤣🤣🤣
Once I buy my house and build my shop I'll be putting together that wire spool set up.... Genius!
@FUDDLEYP JONES that is true but I do car stereo stuff really often so for me spools of wire would be really handy
I did this job on my Celica Alltrac st185 about a year and a half ago. I did use a donor harness from an NA automatic but I still had to redo all the injectors,coils, and cam/crank sensors. I think studied the factory service manual for about a month before I dove in and it still took me almost 2 weeks to get it all proper.
Mine took close to 3 months once I started because day job and life and screw ups and editing. It took me years of fixing and poring over the service manual, and battling never ending problems to motivate me to do this. I confess that vendors still having the parts to do it was a huge motivator, but if that's all it took, you make Thomas Edison look like Slowpoke Rodriguez.
@@Jafromobile well I did use a shortcut with another harness, mainly because of cost. Sourcing all of the wires and connectors added up real quick. Main reason I did it was for the body harness thats tied in to the engine loom. There was very little info on it other than what I could find in the factory service manuals.
@@muttenmagroo Maybe it was the same guy that wrote both service manuals? Yeah it does add up quick. I spent over $1,600 making this video. Definitely a big ol' loss, but this needed to be done and put here. It was the body connector for me that made me re-use any of it. If I found a brand new 21 pin connector in any of my searches, I'd have tried a little harder to find brand new RF shielded single-filament 14-gauge wire. Probably only available in a 500 foot spool, and would have spent close to $1,800 instead. Forums are full of "where can I find shielded o2 sensor wire?" and with no good answers. For each of us struggling with this, there's someone out there who knows exactly where to find it.
Felicidades un abrazo desde chile , sigue con su mision
Jafro es un Maestro. Gracias a el pude meterme mucha mano al viejo Hyundai Elantra 1.6 de mi viejo y a mi Eclipse. Saludos compatriota
Saludos amigo
dam. the car is too low and your not short at all, I hope this car deserves all this big work. love your skills good job
"Anybody that is considering doing a wiring job like this...."
me, finishing that sentence : just don't!
:D
Awesome job, but I would not have the patience to do it. Amazing !
Great video. The electrical side of things always appeals to me more than mechanical. It's the satisfaction of finding the fault and fixing
Guinness, ribs, chicken all ready. Now to slip into a chair and watch Jafro premiere.
Who would have thought I just spent an hour and a half watching a video on a wiring harness for a car and engine that I don't have! (probably everyone that knows how crazy I am) Thank you so much for your time and information, so many useful points for doing any engine harness that I actually took notes! Stay safe.
"It's like a fart in a spacesuit" I've gotta find a way to work that into one of my zoom calls...
loved that analogy
I don't have to do a wiring harness, but your thorough, nature, and step-by-step explanation gave me a day that I did not have to take my OCD meds, much appreciated. 😁
Loved the dry humor in this one, laughed a few times at your jokes 😄
The data log at the track joke was funny.
There are very few videos that pop up where I'll drop everything to go watch. Jafro's videos are always one of those. One of those rare ones that you know hours and hours went into the work and even countless more into the editing. I'm not sure if it's because I'm a detail oriented person of just that smooth Jafro voice that gives me a sense of comfort when watching these videos that makes them so enjoyable. Anyway, I love the content and can't wait for more.
aww dude a squeaky shoe is the worst. you sound like a cartoon character everywhere you go
Clown shoes IRL.
Might be time for some new gasket material?
I do have to say, when I was in high school I had a rough understanding of cars, they interested me but I never had a huge grasp of them or love for the hobby for that matter. I own a 1967 GMC 910, after watching cylinder head 200 series and especially the Elantra engine blue printing series (multiple times) I have grown a major understanding of engine building. Using the tech shown in all your videos Jafro, I was able to excel in the world of mechanics especially engine building. Watching you rewire your whole engine loom reminded me of my first and subsequent second (and far better) attempts of wiring. I am now in a career that deals with essentially "ECU's" but for major oil and gas facilities. I will continue to learn and earn more money at my day job which I hope to send some your way as I would not have the mechanical aptitude or technical skill levels I am. You Jafro have made a major impact on my life and these videos are greatly appreciated in the cold winter waste land of Canada!
The Predators spinal rip was priceless 🤣
Finally jafro is back
With a 1-part trilogy!
Guy don't make excuses you're a damn good mechanic and there's people out there that don't understand a lot of things and you just explain a whole lot me being educated in college about automotive it helps me out now having someone like you in the world because since then I've had traumatic brain injury and what you have done has re-engaged a lot of memories where I've lost education by the brain damage now I can reaccumulate my education that I lost through that thank you
Either I'm stuck in an acid trip remembering super troopers, or at 0:21 does he say third care "meow" --- I can't unhear it now.... I've tried listening over and over.
i can't believe i watched a whole hour of this, but it was way better than I thought it would be. I'm a subaru tech and enjoy electrical work, so this was somehow right up my alley.
I’m a woman so it’s harder for me to find what I’m looking for in my late 60’s u have done a great job addressing everything in ur video ty !! I’m Still trying to save money by doing my own van repairs
I saw the length of the video and set it aside, but after starting it I found that it was a lot like being read Dr. Suess at the psych ward... V-E-R-Y relaxing while leaving me with a devilish grin. By the way, I like the homage to the Predator franchise. Kidding aside it's a very concise, and informative video. Thx 4 posting.
I looked at the title and then the thumbnail and took a deep breath before clicking. You're a champ. I'm not going to question why on a Hyundai but you're a champ.
If you're new here, the car has an interesting story. There's a playlist. There's only 2 Elantras that have run a faster 1/4 mile time than this one and they're the same 1st generation model. So because you didn't ask, I didn't answer. Nobody ever saw me here. PS: Thank you for watching!
I picked up an extra wiring harness for my 1999 just for this sole purpose, thanks for the motivation!
From Henrico va., you are a genius , I have always wanted to make my own harness for my 90 tsi. Well done sir
Your wire striping tool is awesome. Nothing better than simple, cheap, and functional.
as a man who has built a few harnesses and plans to build a few more.....
the black wire swap is going to give me nightmares for the rest of my days. i practically yelled "AUGHHHHHHH" when i saw that lmao
Well just watched the whole thing. Thanks Jafro
You are a trooper! That click was a commitment!
That wire stripe tool is ingenious.
The harness turned out better than OEM, you took great care-
with no piece rate or supervisor to worry about.
This is another amazing video, thank you.
I missed the chocolate music.
Home Depot Racing, baby! It did turn out rather well. I admit I ended this video at proof of concept stage. I have plenty of things I'm doing to the Hyundai that don't require a video and aren't directly related to the harness that this caused, but it did turn out REALLY well, and I'm still making it better. Thanks man!
