2023 Interior Lighting wire

Recommended Posts

I want to install running board "Recon Ice lights" to my 2023 GMC Sierra 1500. I have tried to find the wiring diagram on upfitter but everything is way above my pay grade. Does anyone know the location of the interior lighting wire, color code  and plug location. My 2019 was easy. White plug in the module, located on the left side. It was the gray wire. All different in 2023. Trying to connect my courtesy lights to light my running boards.

I have not tested this, but its probably just a 12v dimming signal for the dome lights.
