Notes in Red above.
So the wires for the lumbar do now work!
The wires I have going to the seat back are only red, white, and black. None of them have any stripes. Also, there are no yellows.
I think the two black connectors I have must be for the sensors, and the gray connectors for the heating elements. I have six wires coming from the body. If I hook the red and black wires (seat side, black connectors) to the body side wires for the sensors that would be easy. But I have no idea how to wire the two whites, black, and red in the gray connectors (seat side). I am going to have to go to pull a part, but I have also been looking in parking lots for another one that someone will lat me look under their driver seat without getting weirded out.
