are 1986 mustang gt and 1987 mustang gt computer harness's the same , i just tried doing a mass air swap from a 1989 mustang gt and the harness doesnt plug into some of the plugs near the brake booster and now the car isn't turning over and the fuel pump wont turn on...and his old harness got cut up pretty bad on the way out so i need to get a wiring harness and i need to know what is plug and play with the 1986 harness besides itself
or why a 1989 mustang gt computer harness wont work or what has to be done to make it work?
