Ok like I stated before my car is a 1993 4cyl lx. I plan on running a blown 351 fuel injected. I am going to use a stock computer, with a custom tune. So the car is a 4cyl 1993. I just bought a 1993 V8 wiring harness and computer. It is for a 302 5spd car, that has been verifed. This should plug right into the dash harness, and the headlight harness correct? So it should just be plug and play? I guess I still need to get a fuel pump relay, "that black box thing" but everything else should work correct? thanks, just trying to cure my paranoid mind
