I ran mine out from the door with the other wiring and up to the roof, i used a piece of electrical conduit bevelled off at 30deg,then took the rear headrest cover off and pulled the headlining main shell down just enough to fit the conduit in and pushed it forward while rotating and it came out near the mirror pulled a good thick piece of string back to the rear and the cable forward again,
Job done put everything back
finished!!
cheers
Paul
