okay.. first off.. i have an obd1 gsr motor with an itr head.. im putting this all into a crx... note that this is not my first swap, so im not asking for how to swap it.. its my first obd1 motor swap into an obd0.. wtf do i do with the obd1 plugs that the motor has? how would i do this..? i mean i can run most of the obd0 parts on the motor.. dizzy, alt, injectors etc.. for now, but how about the plugs and etc on the IM etc? help me out guys.. thanks!

 

most of the plugs are the same, u will need to lengthen some and shorten some. Use the obd0 engine harness

the ect is gonna need to be lengthened so it will reach the water neck, instead of behind the block where it originally is. this plug is the dual bullet style connector on the back of the obd0 blocks.

everything else will be pretty much straight forward

the alternator u can use the obd1 just swap over the circuit, as pictured here

If you have done swaps in the past you should know the impotance of doing things right the first time. Doing an OBD-1 conversion will be easier now and save a lot of problems later. IMO it is easier to convert the car to OBD-1 than it to convert the engine to OBD-0.

 

you will need to splice the obd-1 dizzy plug onto the obd-0 engine harness too.

and add the o2 sensor wires.

get an obd0 to obd1 conversion harness

 

well the thing is this also.. jason (blown90hatch) is one of my friends and hes hooking me up with a jumper harness... the car is not located where i am.. i have to drive and pick it up.. well when i drive to pick it up, im bringing down the motor and all the parts with it.. i have an obd0 dizzy that i was going to run for now just to get home.. also a pr3.. i was just curious if it would be any different cuz the motor is an obd1... i mean within the week the car will be running obd1 with a p72 for now..

 

THis is the color matching i had to do to get my distribotor to work with the obd1 conversion. hope that helps some.

Use your stock harness of course. Just get the grey plugs from an obd1 engine for the dizzy. and then match wires like so.

Obd0-----------------------&gt;obd1
thick white------------------&gt;yel/green
white--------------------------&gt;blue/yel
orange--------------------------&gt;blue/green
wht/blue------------------------&gt;white/blue
orange/blue------------------&gt;orange blue
blue/yel----------------------&gt;white
blue/green--------------------&gt;orange

4 wire o2 is very simple. 2 grounds. And then heater and signal.

Keep the obd0 injectors with the resistor box. and you should be ready to go.

 

I have a 88 hatchback with a phat paint job and gsr motor in it and its a cleaned out car inside and out but its an automatic but i want to convert to an manual is it an easy fix or too much money and work juss want some sujestions before i make a decision

Your OBd-1 color are wrong

 

yea..its the only one that worked for me. I tried all sorts of combos...thats the only one that worked.

 

i got the car running.. im still running obd0.. obd0 dizzy, jectors, etc.. etc.. im waiting for funds to come in so i can buy the harness.. it runs good, minus code 14..
