i need help converting my 87 mustang from speed density to mass air. i'm getting a computer from a 91 mustang 2.3 and mass air sensor. how do i do this without changing out the whole wiring harness? also willing to put on a 5.0 mass air sensor if it'll work (i do realize ill need to change injectors either way). i plan on doing this so i can stroke it to a 2.5 and put a bigger cam in it along with a 5.0 throttle body.
