Turn off the inside lights while the car doors are open
I want to be able to turn off all the
lights when I open my back end. The
front lights in the inside especially
won’t do it
Interior lights aren't on a series of wires any more; it's a printed circuit that controls all this. There really isn't any way to get the lights to not turn on without tearing out the interior and adding a bunch of switches at lights. There is one central light control for interior lights and the easiest way, and the most sane way, is to just turn off the switch when you don't want lights.
I know this is an old question, but I actually learned recently that if you put a carabiner into the latch, it tricks the car into thinking the back hatch is closed. Super nifty when car camping.
