i got a 06 p4 and Im trying to wire up some lights to my accessory button on the touch pad. I cant seem to find the switch leg for that button. I got a meter and checked the wires in the harness. There is not a wire in that harness that changed state when turning the acc on and off. I only got 12v on two wires but neither wire went to 0v when acc is off. I done some research and seen where someone said it should be an orange wire but there isnt an orange wire anywhere under my dash. Anyone got any pointers?
