im thinking of taking out my obd 0 harness and putting in a obd 1 harness.. has anyone done this? i rather do this because i dont like running a conversion harness.. with pins falling out all over the place. lol so are there any major things i have to worrry about. i dont mind changing some of the clips if i need to.. thanks guys

huh?

 

pins just dont "fall out" unless you make your own.

what i wanna do is take out the obd 0 harness and put a full obd 1 harness so i dont have to run a conversions harness.. better?

Werd. All brand new OEM parts using the proper pneumatic crimping machine here.

 

lots of people around here have problems with there conversion harness's thats why i dont want one.. i rather just run straight obd 1.. they all say the wires come off the pins all the time.. they wack

 

the conversion harnesses are very reliable if you buy from the right person. completely converting your car to OBD1 by replacing the whole harness would be a pointless waste of time. you're better off buying an OBD1 car if that's the route you're going to take.

 

yea i guess.. but i like my rex lol.. i dont even have my licsense yet.. and i rather just do it and not deal with a cheap conversion harness.. thats always bothering me.. and if get the harness i still have to run all them wires to different sensors and thats a pain. not very good with wiring.. but changing a harness would be hella easier

nothing cheap here man. All brand new OEM parts. The same parts that are on your car now but not dirty and old. Good luck with it. Your nuts if you think changing the complete underdash, engine harness, etc is easier then doing the converison harness. My instructions are easy enough for a terd grader.

running a p30 with blown90hatch's harness no probs. it was so easy and it was the part i was dreading the most, the wiring.

 

idk ill see probably gonna stick with my idea.. to prove yah wrong

 

running obd1 harness will be a lot easier with a ond1 motor....all the plugs will fit no cutting, splicing, or anything...it makes a blot more sense to e then runing obd0 harness and having to change some of the plugs.

 

if you lets say get a b16 with b16 harness and p28 everything is plug and play...now if you keep that old *** obd0 harness which origionally was for a single cam NON vtec motor then you will have to run a lot more wires, change plugs, run a conversion harness and create a big old mess......we dont want messes in nj.

i hope you know what you're getting yourself into. I'm pretty good at electrical and it took me a week to make an obd1 engine harness from scratch for my 88 hatch. Car runs perfect with no codes. After what i went through i'm leaving the inside of the car wiring alone.

 

right now its only a shell.. and i know im getting a obd 1 motor..

 

im not making a my own obd 1 harness... im getting one from a eg

 

buy a quality conversion harness, a good soldering iron, solder, and heat shrink tubing. if you do decide to remove the main harness, be prepared to have your car sitting for a long time. if you change out to an OBD1 main harness, do realize that you'll have to rewire all the lights, the gauge cluster, and the ECU. not to mention much of the interior! and if you screw up, you drastically lower the value of your car.

If your plan is to replace the OBD0 engine harness to an OBD1 engine harness, be prepared to spend a lot of time reading the wiring diagram for your car, and the wiring diagram for the car the OBD1 engine harness came from. not to mention extending/shortening/shielding wires where they need to go. the two main plugs for the engine harness are on the shock towers. whose to say that an OBD0 harness and OBD1 harness send sensor wires to the main harness in the same locations? even going this way, there is a lot of room for serious error.

do as everyone here is saying, get a quality conversion harness. And put it in correctly, without half assing it.

not trying to get smart or anything but why would you make a harness when you can just take one out an si or a gsr or something?

 

It would be a long, pain-staking task to take the whole harness from an OBD-1 car and put it in your CRX. It's not that simple or I would have done it, because I was in your shoes 2 weeks ago. Had a whole OBD-1 car at my disposal (engine donor car) but instead of messing around ripping my dash(s) apart I just bought a harness from Blown90Hatch Awesome harness and directions, and really really fast shipping, not to mention a good price...I suggest you do the same thing I did

 

i never really messed around with this obd0 b/s.....why wouldnt you just be able to run si, or gsr harness...it should be a lot simpler...unless im missing something lol.

 

the GSR harness will fit on the motor fine. maybe only minor problems, but nothing major.

making the GSR harness connect to the main harness where the ECU resides, is a major pain in the ***. the connectors that join the engine and main harnesses together on the OBD0 and OBD1 harnesses are physically different. Theses connectors can not be repinned easily without the proper tools. the ECU plugs are easily repinned with readily available tools.

there's another problem with the ECU too however. an OBD1 ECU uses 4 plugs that all use the same type of pin. an OBD0 ECU uses 3 plugs with two different pin sizes.

again, buy the harness. I'm speaking from experience here.

 

im getting my harness from a eg.. i wont be the one taking it out. the only harness ill be taking out is my own obd 0 harness.. which im assuming it has like little plugs since its so old.

 

everything is gonna obd 1.. which means its all gonna be the same. so i wont have to worry about converting anything..

thanx for clarifying...i will have to take a look at the harness tomorrow to get a little bit better understanding.
