OK, so I was intrigued by this post. 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.
