Ok so which is it we have two different opinions grounded through the frame or the wiring? With only 3 wires at the switch I would think it is grounded through the frame.

So I journeyed to the 1957-9 Mopar Parts Museum (aka my basement) and went to the Power Window department. I removed a power window motor from the shelf and brought it to my test bench. There are two posts on this Dura power window motor. Same for the Auto-Lite. One will spin the motor CW, while the other spins it CCW. The case is used as the ground. Just FYI.
