I have a 1956 ford that I want to install a 1991 F150 351W with the early fuel injection. I have the complete wiring harness and the fuel tank pump and fuel lines, and of course the computer. Just need some wisdom on the electrical end of things, and a wiring diagram. I know there are probably a dozen threads about this if someone could be so kind as to direct me to them I would be very grateful.

 

Your best bet would be to pick up a Haynes manual from the parts store. It's got a pretty good diagram of the harness. It's not a very hard job with proper planning.
