So I have a 1990 YJ and have been researching doing a 302 swap in it. Originally I put money down on a 1986 mustang 302 a couple weeks agobut once we got the motor pulled I found out the block was cracked in a couple of places by the bellhousing
I ended up finding a 1994 mustang that was wrecked and am planning on pulling the motor this Saturday. I'm hoping this one goes better than the last. I plan to pull everything I can off the car and I'm hoping I can use the stock harness/computer. So my question is, can I adapt the 1994 harness and stock 94 mustang computer to work in my YJ? I know the 1994 harness has a lot more to it than the few years before it and I'm wondering if its even possible. The mustang was an auto and I'm pretty sure 1994 is the year the trans was tied into the computers so I am unsure if it will work. I'll be mating the motor up to my ax-15.
Does anyone know if I can get by with the 1994 stuff if I trim down the harness? Or will it cause the computer to go crazy??
I know the 1992-1993 harnesses and AL9 computers are the most ideal for this if I am going to be doing the wiring myself, but I am trying to stay on budget and would rather not have to buy them if I can get by with what I have already. I plan to get a helm manual for the 1994 motor if it turns out I can use the harness/computer since it sounds like their diagrams are the best.
