Ok i have a b18c gsr motor with a skunk2 intake and obd0 injectors and distributor from a b16a. the ecu i have is a pr3. I understand the mechanical part of the swap but do not know anything about the electrical part. the motor has gray plugs. how do i convert the the wiring harness on the gsr to fit to the crx. what do i do with the gray plugs and what hasport wiring harness do i need and what does that connect? any help would be appreciated.
