I've searched the forums for wiring for an '02 Audi A4 to no avail. I'm doing a remote start and need to make sure I get all the accessory wires nailed. Also, I need pointers on disabling or bypassing the factory alarm. Any extras would be nice too. IE: the window up down feature when locking/unlocking the car(default from the factory)

Thanks
