I have a obd1 GSR motor i'm putting into my 00 Civic Si. I have the factory Obd2B wiring harness, will that run my GSR motor with a Obd2a-Obd2B jumper harness with a Obd2A P72 ECU? Or will I have to change a few connectors on the intake manifold and do the crank angle bypass? Any help you can give would be greatly appreciated! Thank you!
