Thanks for the replys guys, one more question my Bronco is a 1992, what years starting and ending will work?? I had a fire in the enigne compartment and burned the engine wiring harness. It's 4x4 and has a/c, I guess my main question is I have access to a 1997 F150 truck engine and was wondering if that would work.

 

A 97 won't cause that was the new body style with either a OHC mod motor or the 4.2L v6
I would think about from 88-95. give or take a few years.

 

Ditto, 97 is not the same animal at all. BRK's model year run is right but the harness will have to be from a truck with the same engine. The 302 and 351 all have slightly different harness configurations based on sensors and will not interchange.
