Tried that quickly (Connector A to Pin 86) and no luck. Dug this out of the FSM, for the factory wiring harness.

Looks like with the original harness, the yellow wire at each switch is the input of the 12v.

I know I have all the facts staring me in the face, but any other suggestions? I'll check in the morning to see if the relays are clicking, but with the original harness in place just last week all 4 windows worked (from the master switch and from each single switch) but they were painfully slow when I met up with DennisH and had to put them up in the rain.
