In the Caprice that circuit is called LED backlight control. On a 2014 I would imagine the closest place you could tap into it would be the back of the HVAC controls. Looks to be a white and yellow wire at the HVAC panel plug spot 9 :I still need to hook up the bulb for the gear indicator on the shifter to the lights.
Is there a storage bin in the Camaro COnsole?? It have a light in it?
