Was wondering if anyone could give me some pointers on swapping in a 89 Mustang 5.0 motor into a 70 Bronco. More specifically about what you did with the wiring harness ect. The Bronco has a NP435, and from what I understand the Motor mounts and Transmission should bolt up. Any adivce/input would be greatly appreciated.
Check out http://www.fordfuelinjection.com/ if you want a simplified harness that eliminates alot of the extra junk. It will also be real clear on which wires to tie into your stock harness..
Hit classicbroncos.com and broncofix.com for some good EFI info as well. Its a real common swap and well documented. I put a 351 lightning in mine and then converted it to mustang mass air and its all wired in nice. I think this winter Ill upgrade to the FFI harness in order to clean up a bunch of stuff...
I just finished swapping a 5.0 out of a 92 Mustang into my cab truck. Here is some info I have saved:
There are two suppliers (Painless and RJM Technologies) selling ready to go wiring harnesses for about $500. Another option is to buy the Ford Racing harness from Summit racing for $210. There are three parts to the 5.0 harness. The engine part, the main harness that connects the computer to the engine and to the car, and the O2 sensor harness. The Ford racing harness is only the main harness, and it requires cutting a few plugs off and wiring into your vehicle. I decided to modify my stock harness. Here are some links:

Why the fuck would you do that when you can use the stock harness? :shaking:
