Hey guys, and could use a little help. I've installed my new dvd stereo receiver and it all works fine in just missing one thing. There is a wire to hook up to the parking brake wire, I'm not too sure which one that is though. If anyone can tell me where I can look for it that would be great.thank you

 

Depending of the head unit most of the time you can ground the parking wire off the radio straight to ground; if not put a switch between the ground and parking wire and use that to toggle the parking wire
