I spent alot of time researching on this engine swap and was pretty confident when I started it but I've just came upon some conflicting information. Im putting the efi 351 out of my 1990 bronco into my 1986 f250 which had a efi 302. The wiring harness for the 302 should plug right into the 351 and then I would just have to plug in the 351's computer and Im good to go, right? I just got done reading that the wiring harnesses are interchangeable from 87 up, that the 86 was different. Is that true? Thanks for the help.
