My question here is, I have a 99 Civic Si wiring harness (which is OBD2B), an OBD2a B18C, and a OBDI car. My goal is to use this harness and connect to an OBD1 ECU (P72). I heard rumor that I need to change the dizzy and injectors. True? Or could this just be wired up and used with the ECU? I would think I could just use the ones I have and wire them up, but I want to make sure before I kill something. Also, I been reading a few things and I am confused about something. Do I use the Integra rear mounting bracket or an Si bracket? I know I need the Del Sol AC bracket though.
