Most stereo systems need to have the wire that supossodly goes to the parking brake wired. What i would do is put a hidden witch under the dash or some where and take that wire and run it to the switch then you need to ground the wire. The parking brake switch is a ground wire. it is set there so that you do not watch movies and what not while driving. you put the switch in so that you can show the cop that you wernt watching a movie while driving. if you dont care just ground the wire
