can anyone help me to certiify exactly what engine harness i need to run this motor correctly in my 90 crx si?? my mom is going nuts with all the parts in the garage and i need to get this stuff up and running before she has another cow......i have been searching and collecting parts for weeks now and i cannot find this info anywhere on the net... not very many people have this motor in these cars running obd 0.......thanks for your responces in advance

 

OBD0 PR3

 

modify the 90 crx si harness

 

can anyone specify what plugs i need to modify on my stock harness? i am aware that the dissy is different but are there any others that are not the same or that do not plug in?

 

To run OBD-O on that OBD-I GSR engine, you need to find an OBD-O B16A distributor (LS can be modified to fit), add wires for VTEC and the knock sensor, and run a PW0 or PR3 ECU. OR, you can run OBD-I easily by using an OBD-I Computer (either the B17 one or the Del Sol VTEC one) and splicing your stock CRX harness distributor plugs into the B17's distributor (they won't match up otherwise).

 

is it possible to just extract the pins and change the plug they are in to?

 

Get a conversion harness from rywire.com. It will save you a lot of the hassle of wiring up your car.

Plus, you can run it obd-1 like it was meant.

 

Run it exactly like you would with a B16A in your 90 CRX! OBD0 is good but if you already have the OBD1 distributor, get jumper harness! What ECU do you have?

Stay with the obd1 the B17 is set for already. You would be downgrading by going back to OBD0, plus all the hassel of getting a new distributor, ecu and messing around with harness.

 

my friends shop said they could chip my pm6 90 ecu with parts out of the auto computer to run the dohc vtec for 150 or i can get a chiped obd 0 b16 ecu off another guy for 200

plus i can swap my dissy basically for free and use my stock harnesses for free too

common guys this is all my marbles please help

pm me if you have any question if you chose to run obdo.

 

why not just go obd1? it seems like itd be easier. just get the harness and ecu right?

 

as simple as it would be to convert to obd 1...it will cost me more moula i dont have to spend right now! so i cant afford not to let this opportunity of learning to pass me by.... i know it can be done so i want to do it and thats why im here thanks for any helpers guys
