    Hey guys, I'm having a hell of a time identifying this wire harness plug. Anyone know?

    It looks like the cruise control wire bundle (comparing colors). If it is, it will come out just below the wiring bulkhead under the wiper motor and the connector you show will go to this connector.

    Thanks for the reply @Scott91370. Yes, the wires do seem to match up but the connector looks to be 2 big to fit into that end in your picture. I wonder if they changed connectors through the years. I can try matching the wires up and connecting them individually.

    I think you are missing harness #6. The flat plug fits into the back of the cruise control unit.

    @Craig 85 , that makes sense. I'm missing that whole cruise control unit. Thanks so much!

    The connector in your picture goes to the connector in the top center of my pic then becomes the one I am holding which plugs into the cruise unit.
