The harness for the headlights should be the same, except I think you won't have any fog lights if you use it, not sure, as for the computer it might be the same harness, but then again the engine the harness is for has half the cylinders the engine your using it with has, so it might not work, hopefully someone with more experience with fox body harnesses will speak up. Good luck!I need a little help. I am swapping my 88 gt to mass air. I have a wiring harness for the computer side. But the harness on the driver side that goes to the starter solenoid, coil, and headlights in the car is hacked up. Will the headlight harness from a 4 cylinder work for the driver side. Also if I end up needing the one for the computer can I use the one from a 4 cylinder. I know that the fuel injector harness will be different on that side. Thanks in advance.
