1978 Trans Am engine bay wiring diagram
« on: July 25, 2019, 10:47:22 PM »
I bought my car recently minus the engine and transmission. The seller cut all the ends off the wires atr the connections so all i have is a bunch of wires, different colors, but no idea where they go because the ends with the connectors have been cut. Does anyone have a complete engine bay diagram for a T/A with a 400 and automaatic trans (1978)?

thx in advance

PM me with your email, I'll send a large colour diagram. If they are all cut, you may end up well ahead also obtaining a good, used and complete harness instead. It isn't hacked up plus many of those plugs are hard to get. The plugs themselves will cost more than the harness.
