I need some help swapping a seat out of a Mach 1 in to my 98 gt. The wiring harness does not match up. The only plug that is in the car is a female one with 2 slots. The wiring harness on the new seat has a male 4 pin. Any advice? I'll try to post some pics soon.
Put it on the manual slider then. Unless you really want power seats, in which case, you'll need to find the wiring diagrams for the Mach1 and see what it needs. The '98 harness is just going to be 12V and ground, I believe - a quick check with a multimeter will confirm that if you don't have diagrams for it.
