Default obd2 to obd1 conversion in eg hatch

this is for a gsr swap in a eg hatch

i have heard that doing the conversion to obd1 you will need obd1 ecu, injectors, and distributor if i am right?

the only problem is i believe i have an obd2 engine harness, obd2 distributor and injectors. running with a jumper harness to obd1 p72 ecu.

i have no check engine lights though and my car runs fine

so im lost there haha

im not too knowledgeable on this subject however i might throw some insight here.



your vehicle is already obd1

you have an obd1 ecu

but an obd2 dizzy and wiring harness.

i didnt think the obd2 wiring harness would work with an obd1 ecu ( i might be wrong)

did you do the swap? if not the other person may have rewired it already to work

why would you have a obd2 harness in a obd1 car?
how many connectors does the distributor have?
also. what color are the injector clips?

You can use the OBD2 Injectors distributor and alternator so long as you use a '96 - '01 Integra engine harness. The Integra harness is a direct plugin at the shock towers. You then simply use an OBD1 ECU. From the sounds of it this is what you have now.
