Im swapping a b18c in a 88-91 civic dx. I was wondering if its possible to switch to obd-1 without converting to to mpfi by using the complete wire harness from a 92-95 civic. I want to use the engine harness and in-cab harness from an EG and use a p28 ecu. Is it possible and what else would i need.

I would be completely eliminating the EF wiring from engine down and using the EG wiring. Let me know what u guys think. thanks
