I am in the process of converting my 91 Notchback 2.3 to a 5.0. I have a engine harness from a 1989 Gt that I wanted to use but it seems the connectors by the brake booster are different. My 91 has a single brown 8 pin connector and the 89 harnes has two black and gray connectors. Can this combo be made to work and does anyone have a good wiring diagram of both harnesses so I can hopefully splice the two together?
