When I put one probe on one post and one to metal on the door, I get a reading in one position and not in the other with each post.
This makes me think that each of these wires is the hot side and the ground is the door. Comments welcome.

I was under the impression that depending on what way you wanted the window to go the switch just reversed polarity. If you test from the terminal to ground you still should get a complete circuit but only on the wire that is activated at that time.
