This is for your car DVD player right, so you can bypass the parking brake? Any toggle switch at a car parts store will work fine - it doesn't have to be illuminated (that would serve no purpose in this case anyhow). Just a simple on-off $3 switch will work fine. Take the peach wire, extend it for ample wiring reach, run it to ground, figure out where you're going to mount the switch and mount it up, and cut the wire at that point. Put male blade crimp-on terminals on each of the cut ends, and plug them onto the switch, and you're done.
