If I can find a mass air 4banger, will the wiring harness from computer to under hood work on a 5.0? The mass air conversion I just tried...the harness I have is from 92 or newer and its not working? my fuel pump won't come on and I've checked everything..the wiring is ****ed and I don't feel like dicking with that ****ty wiring harness anymore. I wanna find a harness from an '89, but if its off a 4banger will it work? thanks
