DP Video car system to play video

look at the install diagram(wiring codes) that came with the unit. if it has a wire that's designated for the parking brake (allowing you to only watch dvds while brake is engage) take that wire and instead of hooking it up to the parking brake, ground it or put an in-line switch between wire and ground so you can turn that function on and off. warning!!! watching while driving is illegal in most states

you need to get a video cable and hook up the ground on the back of the radio

Hook up the brake wire(pink wire) to the ground(black wire) also when installing to your wiring harness. Picture now shows.

There is a wire that has to be connected to the handbrake wire(gound).
the wire normaly is green
Simple as that.
