Thanks for that great info!! I wanted to get rid of that ugly box. 😁 I'd like to eventually get a tucked harness too so for me it was about trying to get the bay cleaner.
It's required to go obd1, but no added benefit stock. However to make it easier to tune, going obd1 is the way to go. Not many options, if really any remaining at all to tune obd0 ecus.
I should've phrased it better. Are you familiar with the 2 different types of injectors? One works with a resistor box, the other doesn't. He is correct in his statement, I prefer to use obd1 injectors as you'll then have the clips needed for a wide range of other "upgraded" injectors. What setup are you going to have?
I never comment on yt. But i gotta do it right now. Theese videos are the best ef tutorials on the Web. Seriously Man keep up the good work. Hands down.
These how-to vids are gold. I wish more creators could explain this clearly. Of all the YT car, "Senseis," I like you the best. Clearer than Chris fix. Far less annoying than Scotty Kilmer.
Other than not being able to say " ing " these videos are the best most informative videos on TH-cam by far. Keep on makeen these vids. Loveen it so far.
Great tutorial! Just want to note one thing: there is a bad batch of eBay harnesses, mine (and others on the forums) had OBD1 pin B3 (pink) in wrong place. It should be one slot to the left, B1. This is the injector ground. I was getting crank but no start until I fixed that.
I wonder if this was my issue with the hamotorsport I had no spark ever fuel and crank couldn't think to continuity test me adapter from that ground pin to injectors I would have found where it was and should be
Same here.. b5 (obd0) to a16(obd1) missing alternator wire making me stall at lights coming to stops and ckp and cyp come out pinned wrong ..and they are splicing into wrong wires or sensors
Godsend for this. I'm doing this conversion for a D series VTEC motor, but the concepts are all the same. Many videos for this on YT but they seem to be hillbilly edited, put together, and explained. Yours is great, thank you!
For everyone wanting to do this conversion for the cleanest result. Don’t cut your wires!!!!! You can de-pin every plug and change the plugs over to obd1. Without ruining your harness or having to solder. The only wires that will need to be soldered is the 4 for the new o2 and the 2 for the vtec solenoid and pressure switch and 1 for knock sensor. Single cam motors 92-95 don’t need knock sensors The only time you’ll need to cut wires if you’re doing a dpfi to mpfi on obd0 Automatics can also do the mpfi swap into Efs as well non vtec and vtec A stock d15b2 crx dx bottom end with 1.6l zc non vtec cam slapped into the head converted to mpfi and a pm9 ecu header and short ram will hold its own against a stock crx si. It will pull from it on take off And a d16z6 conversion with auto p28 ecu holds its own as well While autos aren’t the fastest there’s a bit of fun to be had for those who don’t want to drive manual or can’t.
I just did this to my 91 hatch last week this video would have come in handy then but me and my buddy figured it out, I love your videos they have helped me out a lot while working on my ef
Phew... Glad my customer sent me this! He's on it! I thought the additional wiring was for radio when I read them. Lol damn conversion came with no basic instructions, like wire indication.
no need to swap injector clips. you can use your obd0 injector clips on an obd1 injector. you just have to trim the inside piece. a lot cleaner this way
no. i trim the inside of the obd0 clips. i use bosch ev1 (same as obd0, hard to find new obd1 specific clips idk why) and just trim the inside corners of the center pice and done. use my trusty dremmel. i can email you pics if you like.
Awesome, please!! garagebuilthondas@yahoo.com. I was looking at getting one of your wiring harnesses when you had them on sale a couple weeks back but didn't have the money to spend. I'll definitely be getting one in the future! I didn't know you followed me on here and am flattered that you do, thanks! I gave you a shout-out in a video a few weeks back where we installed a JDM front end on to my friend's crx, you had made the headlight conversion wiring harness for him. 😀
Greetings from Northen Arizona, Great video! I Feel confident now on converting to obd1. I dropped in a Sir 2 b16a in my 91 si hatch. Gonna run the jdm p30 for now. I have a p28 gonna have it chipped with a b16 base map. Wish me luck!! Nobodys hardly rocking the EF/ED Chassis these days.
The combinations of errors of these ebay harnesses is crazy.there is a bad batch scenarios where sensors are pinned in extreme wrong places and missing wires..in my case my 1st ebay ecu jumper harness cyp and ckp came out with the wires being pinned wrong.and missing a alternator wire 5v reference..i bought a 2nd one and that one was worst.so i took a wire out of it to install into my first harness which was alternator signal wire b5 to a16
No one does that..however if you have everything on your engine or your entire engine is out of a 96-01 then you need obd2 engine harness with obd1 ecu plugs
Hey bro where did you get the diagram for the extra cables? I have a b16 on my CRX but I wanted to check if everything is plugged the same but I can’t find anything to see the diagram. Thanks bro & cool video.
Hey Jon not sure if your still reading comments on this one but it was a great video! Quick question about the 02 sensor, where exactly did you put it and did you have to weld a bung on?
@@GarageBuiltHondas if I were to go ls vtec what ecu would I need to run. So B20b block b16a2 head what ecu could I run ? That’s the hardest part about figuring this all out. I’m new to this stuff so I don’t know much
Did that's with the mpfi swap on my zc single cam EF. But won't start. When I turn the key, there is no cel. I'm assuming I don't have power to the ecu or it's fried. Can anyone help?
Hello, very informative video, I have bought a converted civic to obd1 and o2 sensor is actually with only one wire coming out of it, it started to throw code 43. Can it actually be ok if I put other same one or should I look for wires that should be for the sensor you have and use the one you do?
Ones again my dude, You killed it haha! Good shit man! This conversion obviously gives you some power gain but did you notice any? Dyno tune very soon im sure?
Dude, it felt much stronger at the track. The biggest inclination was this part of the track where it's a long straight, I normally would get to like 95mph but I seemed to be hitting close to 100mph which seemed different. I did however than my fastest outing ever! It feels really good!
Garage Built Hondas Haha that's what's up dude. Tune it now and get all the horses out of your bolt ons my dude. Since your obd1 now. With this obd1 conversion you're definitely getting more out of this motor. Tune it with Crome or Neptune.
I can't wait, been talking to RT Motorsports also and may try out a COP setup before tune but after cams. Hoping this motor is pulling hard by the end of the summer!
Yes, I've had them since last summer. Was something I wanted to get in earlier but just have had so many other things I needed to finish. If I wouldn't have swapped shells I probably would have been done already too.
I have a SOHC ZC (non vtec) and I’m going turbo. Can I just swap the ecu with a chipped obd1 with conversion harness, obd1 distributor and conversion plugs?
Those eBay distributors really suck on timing and injectors only change if you don’t want resistor box or want new injectors and 4th gen Accords have easiest o2 to get integras are a pain due to the connector being in the dash
Hey i was curious, does it matter which black wire goes to which wire on the little extra harness for the o2 sensor? Got a boosted Da, and this is the last thing i need to do before going down to get tuned d:. Btw thabk you for answering everyones questions, and having such an in depth vid o:. Subscribed for sure

Garage Built Hondas I’ve checked that . And the empty slots of c1 and c2 are ran to the left over two wires off the dizzy . Blue / yellow - blue / green
Hey Jon, Thanks for all the helpful info! Quick question... If I buy a 4wire o2 from an auto parts store, would It be 1 white 2 black and 1 random color on any sensor I get?
Those ebay distributor have left me screaming bloody murder to many times. I have been hoarding well known oem ones for years. Hopefully yours treats you better than they have for me
So for my understanding is if im using obd1 injectors than i have to delete the resistor box? But if im using obd0 injectors than i have to keep the resitor box?
I have been watching you for a couple years and I am wondering if you can convert a 1.5 liter Dx digital injected motor into a coilpack instead of wires.
I'm doing this conversation and I bought obd1 injectors and went to change them out and the plugs fit without changing them they just plug right in I checked and the injectors I pulled out are low impedance
Great video, I just this same exact swap on my crx, having difficulty with starting. Does the obd1 ecu have to be P75 and does it have to be basemapped aswell?
@@GarageBuiltHondas sorry about that, yeah I have a b18 head with a b20b4 block, everything stock injectors intake etc etc. My crx si had its original d series motor obd0. I did everything you did step by step except I had a different obd1 ecu. The ecu I purchase the guy said it was a p28 chip in an civic vtec. That why I ask about the ecu being a p75 and basemapped. Cause the car cranks and seems like it wants to start but doesn't. CEL light turns on but off after crank no codes. Cars has spark, fuel, and compression. I triple check the timing on cams and cranks to be all line up. Suggestions?
Nice video I'm considering doing this to my ef, only question I have is won't the ecu light be on since I'll be using a cable vtec vss instead of a eg obd0 vss?
I'm a bit confused by the discussion on the injectors. I have a 1990 CRX Si, and I'm putting a '98-'01 H22A, which I guess is OBD2, so should I go get OBD1 injectors and adapt my D16 injector harness to those? Or can I run the OBD2 injectors?
Which ECU are you using? Use the corresponding injectors to go with your ECU. You can use whatever you want depending on any conversion harnesses you want to use. It's up to you.
question where would i plug the green wire the iab on a gsr intake because i cant find anything on it and my vtec wont engage and everythings right i just dont have an 02 hooked up atm
What's up Jon I have a question for you about the suspension on the wagons. Is there any other good coilovers besides the function ones. Is there a part number for them. Thanks
Hi mate, Hoping you still read these comments. did a JDM D15 swap dual vtec, into a 1991 HF CRX. Have the Rywire harness, everythings hooked up. No resistor box due to obd1 injectors. We are not getting any injector pulse, car starts on starting fluid but wont start without it. Has spark and fuel, just seems to be an issue with the injectors not pulsing. How do we fix or trouble shoot this? cheers
12:22 why not the yello SCS wire? do you not read engine codes? ive got a b20vtech im trying to see if i can get engine codes, ive tried jumping d22 and d04 on my p28 ecu but it just gives me a solid cell. maybe its because the engine light on my 88 civic was never meant to blink out codes? or perhaps it has to do something with the jumper harness to the ecu? also noticed that there was a wire piggy backing off the d04 wire, anyways any ideas or suggestions is appriciated.
Im in the middle of all this obd1 conversion with my 89 prelude obd0. What do you do with the external coil pack/wires & the Igniter unit that sits on passenger strut tower. You didnt go into much detail on that when you switched distributors.
have a 91 crx converting from obd 0 to obd 1 theres 1 problem im going to run into do i need a adaptor of some sort for my alternator plug any help would be awesome subscribed and liked keep the videos rolling thanks
Well i got one question answered. The other one. On your fuel rail and guage. I see you have a high flow rail in the video. I did the same thing. But when i had the guage on the fuel filter it would register as around 40 psi. But when i moved it to the rail it wont go over 25.5 or 30 psi. I think i saw yours do that in the video but im not sure cause its so quick. Is this normal?
Best video I have seen so far. I have an 88 civic hatchback and I am doing a d16z6 conversion would the process be the same and is it the same harness. I do know the ECU is p28 and if it's not the same harness how do I find these?
Hello, nice video but I have some little different questions. Im running eg4 (dpfi OBD1 sohc) and I'm planning to put D16A9 (mpfi OBD0 dohc), so i need (want) to chage motor wiring to OBD1, So I need to replace distributer with OBD1 one, replace thermostat with OBD1, use OBD1 injectors, 02 sensor with 4 wire (instead the OBD0 with one wire)? Im planning to use d16z6 motor installation wires and my tranny (because I want to stay with hydro not cable one). Do I need anything else? Do i need to add some wires to my original car installation because dpfi to mpfi? (Car installation is stock from b2 engine, and the motor installation will bi swapped with d16z6 one. Also which ECU i should run? Can i use harness OBD1 to OBD0 ECU? Or i can run some other OBD1 sohc mpfi ECU like from d16z6 or d15b7? Thanks a lot. Greetings from Croatia!
You'll need to first do a dpfi to mpfi conversion and also use the obd1 conversion harnesses. That'll get you set up to running the engine correctly. Easiest option would be to use your existing wiring harness and convert it to be mpfi. Using a harness from an mpfi car will not work unless you use the underdash harness also.
On the obd0 to obd1 ecu jumper harness.. Ive just got a single cam D16a swap. Do i need to do anything with the intake air bypass signal wire? Or is that one im not gonna use.
Hey I love your videos and I'm doing this conversation soon I have a question tho with my obd0 Honda crx it has a mpfi version zc motor and when I drive the car the check engine light comes on but I don't have any lights coming on on the ECU at all it has the window on it but when I shut the car off and start it again the check engine light is off till I drive again I want to get this figured out before I do the conversation any ideas on what it could be
The person I bought the car from did the swap the ECU is unbolted from chassis the swap looks really good some wiring is a little funky under the hood fan is hard wired and most oem wiring is brittle enough that it breaks when moved the car starts and runs fantastic idles perfect and everything when the check engine light comes on it feels like maybe a few horsepower loss but again no lights anywhere except check engine light
It doesn't. It's how the new injectors power supply need to be since they are a different kind of injector. You're going from "peak and hold" to "saturated" injectors.
How do you check engine lights with swaps? I have 91 wagon with a z6 swap. No light on ecu cause of obd1. But it’s not flashing engine light like obd1 does.
Nice work jon but not necesary to change your injectors to obd1 you can leave your obd0 and resistor box and it will work fine💪👍
Thanks for that great info!!
I wanted to get rid of that ugly box. 😁 I'd like to eventually get a tucked harness too so for me it was about trying to get the bay cleaner.
Is there any added functionality with the OBD1 injectors or no difference at all?
It's required to go obd1, but no added benefit stock. However to make it easier to tune, going obd1 is the way to go. Not many options, if really any remaining at all to tune obd0 ecus.
@@GarageBuiltHondas Ok, so the previous comment (RT Motorsports) saying it's not necessary to change them when converting to OBD1 is incorrect?

Great video!! How did the cheap distributor work out?
No issues!
Great video, I just this same exact swap on my crx, having difficulty with starting. Does the obd1 ecu have to be P75 and does it have to be basemapped aswell?
You didn't specify what engine.
@@GarageBuiltHondas sorry about that, yeah I have a b18 head with a b20b4 block, everything stock injectors intake etc etc. My crx si had its original d series motor obd0. I did everything you did step by step except I had a different obd1 ecu. The ecu I purchase the guy said it was a p28 chip in an civic vtec. That why I ask about the ecu being a p75 and basemapped. Cause the car cranks and seems like it wants to start but doesn't. CEL light turns on but off after crank no codes. Cars has spark, fuel, and compression. I triple check the timing on cams and cranks to be all line up. Suggestions?
Try a known working stock ECU. Nothing chipped.
Great, can you provide link for buying the injector clip.?

I assume you did the dpfi to mpfi conversion?
Great video definitely subscribed to your page. Great build. Keep it up bro.
Will try my best man!!
Nice video I'm considering doing this to my ef, only question I have is won't the ecu light be on since I'll be using a cable vtec vss instead of a eg obd0 vss?
No. The speedometer is still working.
I'm a bit confused by the discussion on the injectors. I have a 1990 CRX Si, and I'm putting a '98-'01 H22A, which I guess is OBD2, so should I go get OBD1 injectors and adapt my D16 injector harness to those? Or can I run the OBD2 injectors?
Which ECU are you using? Use the corresponding injectors to go with your ECU. You can use whatever you want depending on any conversion harnesses you want to use. It's up to you.
question where would i plug the green wire the iab on a gsr intake because i cant find anything on it and my vtec wont engage and everythings right i just dont have an 02 hooked up atm
21:55 any insight on installing a 3 pin dlc ? was looking to use a hondash device
I don't have any experience with that.
What's up Jon I have a question for you about the suspension on the wagons. Is there any other good coilovers besides the function ones. Is there a part number for them. Thanks
Coilovers are all preference. All of them for the 89-91 Civic/CRX will fit. It really depends on your budget and what you want out of it.
OK so I won't have any issues installing them on a wagon. And thanks you're videos are grate... Keep it up... 👍
Did you need to do the point fuel injection multi-port fuel injection conversion? Or was this on an si
This is an Si. You'll have to do the mpfi conversion before doing this. th-cam.com/video/igGZthAHGSI/w-d-xo.html
Hi mate, Hoping you still read these comments. did a JDM D15 swap dual vtec, into a 1991 HF CRX. Have the Rywire harness, everythings hooked up. No resistor box due to obd1 injectors. We are not getting any injector pulse, car starts on starting fluid but wont start without it. Has spark and fuel, just seems to be an issue with the injectors not pulsing. How do we fix or trouble shoot this? cheers
I'm unsure. Sounds like it may be a harness issue. You should contact Rywire.
What would you add too this for doing multi point injection swap at the same time?
All the required MPFI parts. th-cam.com/video/igGZthAHGSI/w-d-xo.htmlsi=wvee2t76wAXQgE7i
12:22 why not the yello SCS wire? do you not read engine codes? ive got a b20vtech im trying to see if i can get engine codes, ive tried jumping d22 and d04 on my p28 ecu but it just gives me a solid cell. maybe its because the engine light on my 88 civic was never meant to blink out codes? or perhaps it has to do something with the jumper harness to the ecu? also noticed that there was a wire piggy backing off the d04 wire, anyways any ideas or suggestions is appriciated.
A13 my guy
Im in the middle of all this obd1 conversion with my 89 prelude obd0. What do you do with the external coil pack/wires & the Igniter unit that sits on passenger strut tower. You didnt go into much detail on that when you switched distributors.
Couldn't tell you. These cars don't have an external coil & igniter. I'm unfamiliar with those Preludes.
@@GarageBuiltHondas thanks anyways man, im gettin it figured out
have a 91 crx converting from obd 0 to obd 1 theres 1 problem im going to run into do i need a adaptor of some sort for my alternator plug any help would be awesome subscribed and liked keep the videos rolling thanks
No. Obd1 alternator have the same plug.
Thanks your awesome thank you
You're welcome
Hi... Amazing video, loved it. I had a question is it possible to convert 2008 suzuki swift from OBD1 to OBD2?
Possibly. If there is a swift before yours that was obd1.
Question for the obd0-obd1 conversion I have the distributor and the jumpers, do I need to have the ecu in hand for it to work ?
Yes
Can I buy the o2 sensor, knock sensor, etc sub harness separate? I am missing the extension harness….
I don't believe they make a sub harness just for those. Most como only sell entire engine harnesses.
Unfortunately you can't BAR your car in California with the jumper harness :(
So glad I don't live in California.
@@GarageBuiltHondas As you should be. I will be spending all weekend repinning my ecu :)
Oh man, hope it goes smoothly!
Can I use the obd0 harness without doing the mpfi conversion and instead get adapter for the injectors that convert the obd0 injector wires to obd1 ?
Yes
so what wire from the sub harness wires into the second black wire into the o2 connector
Either black. They are both grounds.
Hey I did this conversation and the ingine is flooding very hard to start and when I get it started gas is dumping in the exhaust
You may have a stuck open injector. Wiring is 100% correct?
Can you help me with some questions on a problem Im having with my obd0 to obd1 conversion? I have 2 questions
?
Well i got one question answered. The other one. On your fuel rail and guage. I see you have a high flow rail in the video. I did the same thing. But when i had the guage on the fuel filter it would register as around 40 psi. But when i moved it to the rail it wont go over 25.5 or 30 psi. I think i saw yours do that in the video but im not sure cause its so quick. Is this normal?
No. It should be the same throughout.
I figured out the obd0 to obd1 question i had
Best video I have seen so far. I have an 88 civic hatchback and I am doing a d16z6 conversion would the process be the same and is it the same harness. I do know the ECU is p28 and if it's not the same harness how do I find these?
Same exact process as this video. You'll have to add your vtec wiring and knock sensor also.
@@GarageBuiltHondas I'm new can you specify vtec wiring?
Did a obd0 to obd1 swap on my b16a ef and it’s running really rich and low idle
Was it before?
What ecu did you use? Is the ecu stock or chipped?
Thank you so oooooo much 👍💪💪💪💪
👍
Hello, nice video but I have some little different questions. Im running eg4 (dpfi OBD1 sohc) and I'm planning to put D16A9 (mpfi OBD0 dohc), so i need (want) to chage motor wiring to OBD1, So I need to replace distributer with OBD1 one, replace thermostat with OBD1, use OBD1 injectors, 02 sensor with 4 wire (instead the OBD0 with one wire)? Im planning to use d16z6 motor installation wires and my tranny (because I want to stay with hydro not cable one). Do I need anything else? Do i need to add some wires to my original car installation because dpfi to mpfi? (Car installation is stock from b2 engine, and the motor installation will bi swapped with d16z6 one. Also which ECU i should run? Can i use harness OBD1 to OBD0 ECU? Or i can run some other OBD1 sohc mpfi ECU like from d16z6 or d15b7? Thanks a lot. Greetings from Croatia!
You'll need to first do a dpfi to mpfi conversion and also use the obd1 conversion harnesses. That'll get you set up to running the engine correctly. Easiest option would be to use your existing wiring harness and convert it to be mpfi. Using a harness from an mpfi car will not work unless you use the underdash harness also.
On the obd0 to obd1 ecu jumper harness.. Ive just got a single cam D16a swap. Do i need to do anything with the intake air bypass signal wire? Or is that one im not gonna use.
Hey man I got everything to do this I need to know if I can some information on how to do the wire to the ecu
This video shows how to use the obd1 harness with the ECU.
Would you suggest swapping the actual wiring from the ecu to the engine bay on a civic wagon to obd1
I'd prefer to use the subharness
Garage Built Hondas what subharness are you speaking of this is my first try at swapping a honda. I have a rt4wd wagon and trying to put in a d16z6
The one that I'm using in the video.
Garage Built Hondas so my motor still has the engine harness will that plug into my obd0 chassis harness
You need to clarify when asking questions? Are you saying your Z6 still has the harness on it? If yes, then NO, it will not plug into your wagon.
Is there a reason why you are not using the Knock Sensor??My ecu is throwing the code for the knock sensor, I have a JDM b20b, running p75 like you!!
What's the code #? My understanding is that all A1 & B1 wnfines never had a knock sensor.
Garage Built Hondas im sorry, its not knock sensor, its Crankshaft Position sensor code #4 and also #10 IAT Sensor?? Its currently in limp mode
What car do you have? Which obd is your ECU?
Garage Built Hondas I have a obd1 p75, running my stock si harness
EF SI?
Hey I love your videos and I'm doing this conversation soon I have a question tho with my obd0 Honda crx it has a mpfi version zc motor and when I drive the car the check engine light comes on but I don't have any lights coming on on the ECU at all it has the window on it but when I shut the car off and start it again the check engine light is off till I drive again I want to get this figured out before I do the conversation any ideas on what it could be
Does the red led come blink when you first turn the key?
@@GarageBuiltHondas no
The person I bought the car from did the swap the ECU is unbolted from chassis the swap looks really good some wiring is a little funky under the hood fan is hard wired and most oem wiring is brittle enough that it breaks when moved the car starts and runs fantastic idles perfect and everything when the check engine light comes on it feels like maybe a few horsepower loss but again no lights anywhere except check engine light
Non VTEC zc sohc
Do you think it's the ECU no lights turn on at all ever through the window
nice convert obd0 civic/crx/integra ecu harnesss ok
What is it doing to connect all those wires from the restrictor box? Doesnt cause a short or something?
It doesn't. It's how the new injectors power supply need to be since they are a different kind of injector. You're going from "peak and hold" to "saturated" injectors.
hello, I have the same D14a3 engine from an Ej9 from 1997 and I want to put a d16y8 engine in it which is OBD2, how do I proceed?
How do you check engine lights with swaps?
I have 91 wagon with a z6 swap. No light on ecu cause of obd1. But it’s not flashing engine light like obd1 does.
Flashing will be on the cluster now.
@@GarageBuiltHondas doesn’t flash anywhere. Cluster or ecu
Jumped the connector?
@@GarageBuiltHondas yes sir. Blue connector in pass side. I read somewhere I have to ground b20 I think it was
Not sure why yours doesn't work. Mine works perfectly and the CEL flashes on the engine light now.
I'm swapping a b16a into an 89 si hatch,Since your swapping to OBD1,can u just use 1 O2 sensor?
Yes
