I have just got a DVD Head unit and it has 1 cable which has to be connected to the hand break cable? How can i do it so i dont have to connect it to the hand break cable? Thanks Dave
I think you mean handbrake, and I guess you join the two wires. RTFM. That switch is a safety feature.
it will either want the ground or 12v... up to you which you test first! alternativly as Xen0phobiak said, check the manual- see what it requires!
