The CAN system is connected to it and is showing allot of info in android unit.
Natban has no acc 12 volt cable going to android unit in his drawing.

Yes I can see that, but what I'm suggesting is on the AVIN harness (or whatever brand we're using) Pins 15 + 16 are swapped, so @natban is getting switched powered and not constant, so the the presumable 12v signal isn't coming through when his lights are on/off.
But you're right, perhaps can lines are controlling it... The only way is to test it one by one by removing the cables and trying to get it to work... Unless you're handy with programming and MCU.
At the back of my headlight module I have three wires - orange, grey/red stripe and X other (can't remember right now). From the link above, it seems like grey/red is Illumination (12v variable) whereas orange is switched 12v... But I will need to investigate to be certain...
