Hello fellow Vanners!
I have these cables sticking out from my rear ceiling close to the rear
window, right side is red and gray, left is blue and gray, I don't even know
what was mounted there, but I don't find these wires where the radio is
supposed to be. I'm not much into audio other than bird song, but I want to
mount an LED light and a little fan so I would like some hints on where to
find these wires in the front!

Thanks
Tobias
