I recently installed a front camera and a light bar - the camera switch is backlit like the rest of my switches, but the lightbar switch has to be connected to one of the others to be backlit. The problem is I'm not sure which of the stock wires to tap into. Anyone with an FSM or wiring diagram able to tell me which wire to either the headlamp washer button or the VSC button controls its backlight? Cheers!

 

The illumination for the switch should be green for the positive. Gray is the ground that goes to the illumination control computer and rheostat. Your switch might need to have a separate led ground to work?

 

Which front camera system did u use?

 

Thanks y’all, the green wire was the one!

 

Check this post on my build thread, I've got links to everything I used for the install!
