I'm gonna do this on my crew if I ever get around to it.

It uses 2 relays per window, one for up one for down. Just regular relays, 30 amps I think. Instead of the voltage going thru all the wiring and loosing some by the time it gets to the motor, going thru the relay sends a full 12 volts to the motor. I guess it turns slow ass windows into an upside down guillotine.
