I'm installing a new head unit to replace the factory basic radio. One wire from the new unit must be connected to the parking brake wire. Anybody know what color that wire is? I know I can bypass the safety lock, but I'd rather not. I have teenagers that will drive this vehicle shortly, and I don't want them being tempted to watch DVD's while driving. Thanks in advance.

 

Found it. Not so hard when there is some decent light. Just a single green wire with a yellow stripe at the top of the parking brake switch.
