i have an '03 stx with the 4.6. modified, i also have a 2013 salvaged GT mustang with 11,000 miles with a coyote motor auto 6 speed trans that is still good. i want to swap motors but dont want to swap electrical if at all possible. with some differant brackets for a few items would this swap be possible without wiring pcm ect...?

 

Nope, that will require major electronics mods.

 

thats what I was afraid of being that new vehicles have electrical everything and older models don't. Thanks for the input.
