Installed my back up cam and was unsuccessful with the wiring. My '08 97x has 3 wires running to the backup lamps (see picture.) When I connect the camera positive to the yellow wire the backup light stays permanently on and drains the battery. The trailblazer FSM doesn't show 3 wires in the lighting diagram. Any ideas?
I should add that I'm grounded to the body but perhaps I should ground to the backup lamp as well?
