My friend picked up a obdo b16a motor tranny ecu and most of the harness to day, that he wants to put in his 94 civic dx. I already know that the tranny won't work but i have a hydro tranny that i'm going to give him. I'm also going to give him a p28 ecu and obd1 civic ex full engine harness to use. my question is what all will have to be changed on the motor to make the obd1 harness work? Any and all help on this would be appreciated. thanks.
