I'm having a hard time finding the right information for my questions. I bought an ek coupe with an OBD1 b16a engine. One of my friend gave me a obd2 engine harness and I need an ECU. I read that a p30 would be fine for running a b16a, but it's obd1. Basically, I just need an OBD1->OBD2 conversion so the harness can fit my ECU? And on the engine? What do I need to do for a OBD2 harness to fit on my OBD1 engine?
