Due to my present situation (wheel chair and both hands plasted) I have not had the possibility to make any feather investigation in this matter!
But I'm still curios of what it could be connected to? The factory installed telephone was not connected to this nor the rear seat heater. The AUX heater/ WEBASTO shouldn't be connected, it should have an own wiring harness and so should the rear power seats ( which non of them that I have ), What else could it be? I don't know of any more options for the V8!
