I searched through the FSM and didn't find anything specific to the mirrors and control switch. I am looking for the break down of the 4 wires going into each mirror. I am trying to get a set of Auto Palace mirrors hooked up on my project, however, they have a 3 wire control. Any info would be greatly appreciated.

 

three wire motors use a common lead from the switch. You'll have to experiment to make it work with a stock switch.
