Headliner wiring diagram
Hey guys i'm trying to make sense on the wiring for the roof lighting, I am in middle of doing my headliner in a black Alcantara and thought why not doing something different for the lighting.

Hey Patel, answer in short is yes. Ideally I'd like to know what each of the 4 wire are for. I assume one is ground one is power but what are the other 2? Since both connector harnesses have different colours wires but do the same thing (one is front one is mid-rear photos attached both the connectors do the same thing connect to the lights) i'm not sure what is what. I do have a electricity tester and will use it once I get back in there. For now if someone already knows what each one is that would help tremendously. Thank you,

So they are the 3 light blocks ?
The front one is different as the middle switch sends a signal back to the computer.
It will then turn the lights on or off (and if held in will shut lights off forever)
The center seat row middle switch will just turn that light on I guess
Green/white reading light and mirror lights are live. But get shut off when locked

Black is ground
Purple is + for main lights
green/white is for the reading lights. (+ when unlocked)
purple/blue is the centre switch on the front light, to trigger computer to turn lights on
On my wiring diagram the middle row light only has 3 wires
