WELCOME TO THE JUNGLE! - 85 C10 5.3 LS Swap - Engine / Transmission Wiring + FIRST START! - UTX

- Welcome to Ugly Truck, we got fun and games! We're finally ready to wire up the 5.3L and 4L60E transmission in this 1985 Chevy C10, and we're DEFINITELY ready to hear it run! We take it one circuit at a time, following the wiring diagrams for the 2005 Chevy Suburban 5.3 L59 donor truck, and set up our new fuse boxes. Remember when we said "Relays are your friend"? We meant it! The new 5.3/4L60E takes a lot more amperage than the old 305, but by looking at the power distribution diagrams for the 85 C10 and the 2005 LS, we can use relays to carry that load. Sorting through all these wires and soldering the connectors is a long and tedious process, but hearing the exhaust for the first time was worth all the effort!

On that neutral switch,, what role plays the purple/white wire??? Not needed?? What happen to it??
@@gerardolopez5875 Which circuit are you asking about? If you know the circuit or wire number I'll try to help you out. If you're talking about the truck's original wiring, I'll need to know what truck is and what motor it had in it.
@@UglyTruckExperience @ never mind, its a different harness from a 2001, And 2001 dont have crank voltage from pcm, correct?
Great job guys.. really enjoy your channel. My son bought someone else's project.. an 88 silverado ls swap. Engine runs, but we seem to be having trouble keeping the 4L60 working properly. I would like to see more of how the transmission is controlled by the PCM and how your make it shift properly. Thanks.. looking forward to more content.. God Bless and thank you guys for sharing your hard work.
Thank you! And thanks for watching! When you say the transmission isn't shifting properly, what exactly does it do? Does it shift at all?
I've been doing swaps for 10 years at least, got the fuel systems down, the mounts, exhaust and intake. I've been using aftermarket harnesses and PCM's for all because they have been modified engines I've built. I have a friend that wants a stock 5.3 in his '52 Chevy Deluxe just to push it down the road and I think this would be a perfect time to look into modifying a stock harness, I have boxes of them, and stripping them to the bare necessities to run a reprogrammed, stock PCM. This looks like a really good start and I'm going to reference your other video's. Thanks for the info.
Thanks for watching! Our swaps are mostly stock, so we usually buy a whole donor vehicle and reuse as many parts as we can. We have more swaps lined up, so if there's something we haven't covered, let us know! 😊
@@UglyTruckExperience Just a few tricks like using Corvette filter/regulators and plumbing return lines into fuel fills instead of pulling tanks. I do like the fact you use hard line, I do also instead of draping braided all over the place. Nice Job.

Sorry hit key 🔑 lol
That was a great lesson things that I did not know myself and I’ve been in the business for 40 years or more,Thank you for this beautiful lesson I’m gonna watch the next chapter about your kind bugs bending exhaust making a custom exhaust that one I’m very familiar I used to work the Pipe bending machine I call it that’s fun On some cars I’m gonna go to the exhaust section again where are you Kind folks from?I would love to take a trip to your shop and show you my 61 Chevy I would love to meet your dad show me a trick or two thank you Anthony from London Kentucky
Great video. Beautiful dog. Nice shop. Thanks for sharing
Thank you! And thanks for watching!
Im swapping a Scottsdale thats the same Midnight Blue and Silver. Awesome Videos guys.
I think it's become my favorite paint scheme on these trucks! Thanks for watching!
Great video!! The only thing I would only add that this setup isn't for 2002 and down models
Thanks for watching! This video Is meant to show the process of reading the wiring diagrams and wiring each circuit. The wiring diagrams we used are only specific to a 2005 L59 5.3 and a 1985 C10.
Still awesome video and very informative made me subscribe keep them coming
Thanks for subscribing! We have a ton of videos and projects lined up!
New subscriber you guys have great content no one else describes the wiring as easy as you guys do. Nothing's left out and you guys describe in great detail. Thank you keep it up
Thank you! We love showing all the juicy details! Check out this playlist too... There's more wiring videos and lots of good LS swap info. We appreciate you watching!

Love the effort and info put into these videos. You guys helped me with several questions I had on my swap. Thanks for making the videos👍
Thanks so much, Steve! Glad the videos have been helpful!
Great video! I have an 81 c10 I'm getting ready to LS swap and your videos will help immensely. Thanks for sharing your knowledge.
We appreciate you watching! Best of luck on your C10! 👍
Definitely learned a lot!😎
You said to ask so ...Are you using the stock clutch fan? Interested on how to wire in a fan relay off the PCM trigger wires. I got mine flashed with a low and a high fan trigger to ground wire. Also since I saw your reclaimed oil burner stove.That would be an interesting video on how that works!
This truck is getting electric fans also, so we will have a video on wiring them up very soon! Our heater is definitely "interesting"! 😂 We built it out of some junk we had laying around, but it works great! We'd be in big trouble without it!
This video will be used for C10 LS Swaps for years to come lol
We hope so! I think there are a lot of LS swaps out there just waiting on wires. Maybe we can give them some motivation! 😊
How did you know how many/what wires to put in each circuit? Didnt seam to have patern for injector and coils
Hello Workingman. It has been a while since we did this video, but I would have done each circuit individually with the same protection and pattern that It would have had in the original fuse box or power supply. Would get that info from the wiring diagram. That video, we we're trying to get people interested in looking at wiring diagram and applying it to anything they are working on. Thanks. Jerry and Emily
New to your channel love you guys videos
Thank you. We appreciate you watching.
You guys are the best .you made this build so much easier for me .I have a 1970 c10 that I’m doing the swap to.I bought a 2004 Chevy surb.my question is can I just use the fuse box that’s on the truck?also would I have to flash the computer to make the truck run?
Thanks for watching! Glad we could help! Yes, you can definitely use the original LS fuse box if you have it. That's what we did on our 1970 C10. We talk about it at the beginning of this video: th-cam.com/video/T01jWSJttBI/w-d-xo.html . We send our computer out to a programmer. The security system has to be removed in it in order to start the engine, but you also want it programmed for your tire height, final gear ratio, and what transmission you're using. If you're not swapping the transmission, you would just need the security removed.
New subscriber here really nice contest keep up the good work 👍🏽👍🏽💯
Thanks for subscribing! We have a ton of cool stuff planned! 😉
Since you are swapping to a 4L60E transmission that utilizes a lock-up type torque converter, did you wire lock up through your brake switch? I did not watch the entire video as I can convert factory harnesses to stand alone harnesses on my own. What I DO KNOW for sure is that any vehicle that had a 4L60E, or 4L80E, and probably most, if not all, modern automatic transmissions receive a 12V+ source from the brake pedal switch (when it's NOT depressed) that actually powers the TCC lock up circuit in the transmission. It's pin 33 on the BLUE connector on the 411 PCM's. That pin MUST have 12V+ in order for the transmission to lock up. If no power there-the trans will NEVER go into lock up. You might think... "eh, no big deal if it does not lock up". and you would be DEAD WRONG. If it can't, or does not, lock up, it will over-heat the trans and FRY the transmission on a long drive on the freeway. For simplicity, you can simply wire pin 33 on BLUE connector so that it has 12V+ any time the key is "on" or in the "run" position thereby bypassing the brake pedal switch. However, if you want TCC to unlock when you tap the brakes, you need to go through the brake pedal switch. If you do NOTHING else after reading this-go and verify 12V+ at pin 33 when the key is on. If no voltage-STOP driving the vehicle as you are going to destroy the trans! I see it's been 1 year since you did this swap. Hopefully you have figured it out. For anyone else reading this-take note! My shop is hired to sort out these issues on other peoples LS swap projects and this is the #1 thing that almost every swap needs corrected.
That is correct. We addressed exactly what you are talking about in this video. th-cam.com/video/yHUZ7JfQBbk/w-d-xo.html
Awesome information, thank you. You’re cutting wires like F3, F9, D12, and all of those are labeled on the information you printed. How will you know which wire is where after you install you’re new boxes? You are not labeling them as you go. Will the next owners just need to check for continuity? I’m going to be watching this whole series a few more times.
Hello Gabby. On this truck I ended up going back and using the LS donor fuse box and fortunately had a video to go back to show which circuit I was working with. If I hadn't had that I would have checked each circuit to confirm what I was working with. When I build a truck for somebody else, I always use the donor fuse box with the donor harness and connectors which are labeled. I try to do the wiring in a way that it could be diagnosed like normal later on down the road. Thanks for watching and commenting. We appreciate you watching. Jerry and Emily
Would've been an EXCELLENT video without the HUNDREDS of "uh's' and "ah's"..
Thanks for your feedback.
Good job guys. My wires in my 85 is all beat up and some hanging and headlights dry rotted. I need to replace the wiring. What do you suggest on a wiring product or buying wires and do it myself eventhough, its my 1st time doin any of it
Thanks for watching! I know there are a few good aftermarket harness companies out there, but we've not personally used them. If you're up for it, you can find a full wiring diagram for your truck pretty easily. It's tedious work, but it's also a great way to learn. Either way, let us know how it goes! 😊 --Emily
great work i'm doing a 75 k5 blazer .Using a 2002 5.3 4l60 4x4 want to know which t case to use
I am pretty sure the 75 came with a 205 transfer case, which is a pretty tough case. If you are bolting it up to a 4L60 you will have to buy a kit that has a different output shaft and housing to bolt the the 205 to. I have that setup on our 74 K10 and it works perfectly. The transmission has to be taken all the way down to the output shaft with a new shaft and adapter to bolt to the right hand case. Jerry
I’m still wanting to LS swap to my 85 3/4 ton Silverado ‘diesel’. Is the wiring the same as this C10?
Very close to being the same. The diesel has a hot in run and start wire that comes out of firewall goes to injection pump instead of hei ignition. Other than that it is pretty much the same.
if I buy a 5.3 and it doesn't have the computer should I not buy it?? Thanks 😎 like your video 📹
Does it have the wiring harness? If you have the harness and you know the VIN of the vehicle it came out of, you should be able to buy a new computer for it.
Definitely know what ur doing! Good job
Thank you! And thanks for watching! 😊
Have you guys ever done a sbc tpi installation?
No, but we have a video coming up on installing one in a 78 Trans Am! Thanks for watching! --Emily
@@UglyTruckExperience that’s awesome!!! When is it coming out? I’m in need of knowledge
It will probably be a few months, but feel free to let us know what questions you have and we'll do our best to help!
@@UglyTruckExperience m swapping a sbc 350 5.7 tpi into a 1971 jaguar xj6. The wiring harness isn’t that hard however a few wires need to be hooked up to the jaguar, that’s where my issue is, I don’t know where to hook them up to.
I follow your videos because you make the job so easy to understand and gives me the power and confidence to go out there to work on my project.
Thanks guys! Keep up the good work!
I have never worked on that old of a Jaguar but it should be pretty straight forward. You would just determine the wire that went to starter solenoid and the wire that fed the coil. We own a 97 Jaguar xj6l that we would like to do the same swap. Keep us informed on how it's going. Thanks
I like that fuse/relay box.
On that truck, I ended up going back and using the stock box from the donor truck which is so much easier. I hope you check those videos out. Thanks. Jerry
I'm a little unclear on the multi-relay setup. By using several realys, apparently with the coils wired in parallel, you are multiplying the energizing current by the number of relays in parallel. So, how do you determine if the PCM can accomodate the increased switching load? I would think there's a limit to the current the PCM can sink before limiting or buning up. Clearly you haven't burned the car down, so it works, but is it within spec?
The relays supply power to the individual items that they are running on the engine. The pcm just turns the relay on. Thanks for the comment
@@UglyTruckExperience Yes. I was referring to the energizing coils (pins 85/86). These require some amount of current. Wiring them in parallel requires the pcm to source/sink current for EACH of them. The question was how to determine what the PCM current source/sink capability is so as not to exceed it.
Ok. I get your question now. The next time I'm messing around with a relay I will check its amp draw. I dont remember how I wired this specific one but when what your talking about is an issue I would just use one relay to turn any other relays on.
I followed your lead building my harness. Unfortunately my fuel pump requires a #10 wire with a 50 amp relay at the pump. Is it bad to double relay or would you suggest to undo the fuel pump relay and use it to trigger one rear relay? Thanks
Sounds like your going to be making some serious hp. In this case I would use the smaller relay to trigger your high amp relay back by the pump. That kind of insures that your going to get good trigger voltage on that high amp relay. Let us know what your building that is going to use that much fuel. Sounds fun. Thanks
Using a setup from Tanks Inc. Just a 650 hp rated. They specifically do not state to put the relay at the pump per se. They just want the 50 amp with a circuit breaker before the relay. I was thinking about using an extra space in my fuse box for the 50 amp relay and run the wire to the pump. Is having the relay close a better option?
I just looked at their installation instructions. I wonder why they use a circuit breaker. It really shouldn't matter where the large amp relay is located. I would put it wherever it was easiest to wire and get to if you needed. Personally I would use a fuse close to the battery or power source, not a circuit breaker. But that's just my opinion.
@@UglyTruckExperience thanks. Really respect you guys and love what you are doing. Thanks so much
Thank you again for a great video! Thoroughly enjoy watching your approach and your teaching technique. Really enjoyed this video as I am in the beginning stage of LS swapping a 2005 Cadillac SRX. Pulled the V-6 and tranny, now attempting to mount an 03 5.3 LM7 from a suburban. Figuring out how to wire this thing is keeping me up at night! LOL! Cheers and thanks again!!
Thanks for watching! That's definitely an interesting swap! Keep us posted! 👍
On your comment about a bussed fuse and relay panel...see this. Lookup EATON's Bussmann Series 15303-6-2-4 RTMR Mini Fuse Panel. It's what I have in my own 1978 C10 LS Swap. Great job here by the way.
Thanks for watching! I will check out that fuse panel. The ones we used were good, but we're always looking for other options. You should stay tuned...our next swap is a 78 C10! 😁
Is that a flex fuel engine? if it is what do you do with the sensor
The sensor is not installed and the trucks computer is programmed for a non flex fuel truck. Thanks Jerry
hey, what about the vehicle speed sensor and the torque converter lockup wiring
Hi Mike! What are you working on and what was your donor? We may have a video that covers that. --Emily
Took a 6.0 with a 4l80 out of a 2000 gmcsierra 2500hd 4wd and putting it into a 49 chevy pickup 2wd. When you change the options in hp tuners to a 2wd does the ecu just know to use different wires for the vss? And how to wire the torque converter lockup?
So you are saying that's all I need to do is get that aftermarket fuse box along with 4 relays and fuses, then follow step by step and my swap should fire up? It's a 5.3 with 2wd 4l60e going in a 85 chevy caprice classic
It's almost impossible to do a step by step video because every swap is different. You'll need to know exactly which engine you have and what it came out of in order to find the right wiring diagrams. This video should help you out also. th-cam.com/video/T01jWSJttBI/w-d-xo.html Thanks for watching!
The more videos I watch about doing wiring for an LS swap, the more I think I'm just going to spend the extra money and get a Holley Terminator X setup. It's not that I'm not capable of doing this type of wiring, I just don't know that I want to spend that amount of time on it. I'm already going to have extra wiring to do so I can keep my factory gauges. I also like that with the Terminator X I can program the thing myself if I decide later down the road to add a turbo or an E-85 module or any other modifications that require the ECM to be reprogrammed.
They definitely do have some benefits when it comes to tuning it later on. If you end up getting one, let us know how it goes. Thanks
You know I bought a wiring harnesses with computer from psi conversion, but watching this I might just take the one from donor truck an see what I can do with it for an up coming swap in a camaro
It's really not that bad if you take it one circuit at a time. Check out this video for more info! 😊 th-cam.com/video/T01jWSJttBI/w-d-xo.html

Where did you get the fuse boxes?
Hi Anthony! Here's a link to the boxes we used. Thanks for watching! amzn.to/4a1OZ9x
Well, im convinced that it is easier to use donor fusebox
Definitely! We actually ended up rewiring this truck with the original fuse box before we were done. The OEM box is bigger, but it's so much simpler to add accessories like cruise control and AC. We appreciate you watching!

What did you guys use to program the ECM? I like to do my own thing so I know what to take out or add but it’s pricey to go through HPtuners
We send our PCM's to LT1swap.com. On this truck, we sent him the engine, trans, injector, gear ratio, and tire size info, and had him delete the VATS, rear O2 sensor, and EGR. His website has a TON of great info! --Emily
@@UglyTruckExperience that’s awesome. I was gonna go through them on my first LS swap but I went carb and an mad idniton controller and it ran good but I want fuel injection in my 91 burb…….
How does the truck with his work? I’ve heard AWESOME stuff from him. I have two 411 pcm’s I want him to do. But waiting on get my parts truck when i get home. It’s a 4.8 but it’s free so I’ll run it

hey man could help?
What are you working on?
How can you wire a 5.3 in a 1995 Chevy tbi
Swapping a 95 chevy would be very similar to swapping most any other. A different wire harness and ECM. A 95 may already have 4l60E or 80E transmission which would help. Making everything on the instrument cluster work properly is the biggest obstacle in my opinion. Thanks Jerry
