Sorry I searched, but it was down. I am getting parts together to put an obd1 gsr swap in my 99 ex. Can I just get an obd2-obd1 adapter and use my current harness, or do I need to get the stock gsr harness to run the p72 ecu?

 

you can get the harness to run the obd1 ecu but some of your plugs on the engine harness are going to be different like the plugs for your injectors and such

 

Do you know exactly what plugs I would have to change? How hard is it?

 

Bump

 

Use the 99 EX engine harness with an obd2b-1 ecu adapter, and change the following plugs on your engine harness:

Distributor
Injectors
Alternator
Intake Air Temp Sensor

Add the IAB plug and wiring.

That should be about it, unless I am forgetting something, which is possible..

 

Thanks alot. In order to change them, do I just cut the old ones off and splice then new ones on. Dumb question.

 

Thats pretty much the way to do it..

Good luck..
