I've been doing as much research as posssible before I go into this project and I can't seem to find a straight answer for putting a OBD1 engine in a OBD2 car. First off I don't wanna convert the engine to OBD2. The only answer I have come up with is having to convert my whole dash wiring to OBD1. Alot of people say just get a wiring harness adapter, but I want to use a OBD1 engine harness so that idea is out. right? I have thought about putting a OBD2 end on my OBD1 engine harness then getting a conversion harness to run my OBD1 ECU, but I can't find anyone out there that has done this and documented it. PLEASE HELP, I need some direction is this area.
