I bought a 530t and heard that it can be used to roll all four windows up when your alarm is armed if you sacrifice the ability to roll the windows down with an aux channel or use the one-touch full travel feature. If that is true and someone can explain how to do that, please, it would be helpful. Aside from that, I need to locate some wires in my 2000 Ford Expedition. I need the ground-when-armed wire color, or even the location in the car that I can find this bunch of wires.
