NCV3 Interior Light Info

Thanks goes (again) to Manwithgun.

By then creating your own ground point to serve as the negative, you pretty much isolate the usb load from the BCM that “controls” the dome light switching function. If there are any solid brown wires in the headliner, this would likely be a factory grounding point that can also be used. Add your own switch to open and close either the positive + (red) or negative wires feeding the USB port since most that I have used are internally illuminated.

I have used these for compact switches where space is limited, and their larger big brother when space allows.
