2002 tahoe windows/sunroof

The driver's door window you havet o grab at the switch and run the wires through the boot of the door. I know DEI makes a 4 window up or down but not both. You will need to purchase two of these units and one separate one for the sunroof open/close. You will then need 2 AUX channels on your alarm/RS unit to control the functions.

yeah dei makes a all 4 window p. i just put it in an infinity g20 on sat. it only goes up though. it can be triggered by a starter kill output or by a neg door lck pulse. you only need an aux channel if you are going to put another one in to have them roll down. this model is RLWN4

Twindo makes a sunfroof close module and it is  TS-1A

feel free for any other questions

what do mean

what exactly do u want to do??

No it is not possible. Once the module detects a voltage spike, the unit shuts off the power so whatever window closes first shuts off the power so that the window that is piggy backed will not be able to close anymore.
