auto window wiring

I'm trying to add window up/down to an alarm system without using a module that bypasses the stock functions. It's a 2012 mustang that already has auto up/down on the windows so a 530T module seems to be overkill. Here's the wiring diagram A DMM on bu/gy, the driver up output, shows 12V when the switch is pulled up, then 12V again when switch is pulled up higher to auto mode. When released, it goes right back down. So any idea how this works or anyway to wire something to the auto mode?

You have to go directly to the motor wires in each door. If you can't get at them just forget it and extend the lock time for comfort closure.

Diagram didn't work. Unless it is a multiplexed switch, not sure you can duplicate the behavior easily (or at all). Since it is factory auto-up, you have built in anti-pinch so you are right to some extent that a 530T would be over kill. Problem is whether or not you can simply duplicate what the switch is doing.

Have you even tried to extend the lock time?
