    Old Nash: Yep, I have those figured. There are 2 others going into the convenience block on the drivers side. 1 is the starter solenoid, and the other is ??
    classic79: TCC? What's that?

    I can't read, I see your post that you had these figured out. I see there is purple wire that goes from the windshield wiper motor to windshield wiper switch. Have you check that?

    I'll check the wipers, but I don't think they got disconnected. It should be just the engine connections.
    re: TCC, would a manual truck be wired for it and left loose?

    The TCC wire is purple with a white tracer. Is the wire you have a solid purple or purple with white tracer? The wiper leads goes into cab in same area as convenience block.
    My 92 truck is 5 speed and has a few weather pack connectors (Think that's what they're called) that are not connected to anything and just hang loose. I don't think (maybe wrong) GM had different
    wiring harness back then. If wrong someone please correct.
