In-Dash DVD not working

I am in the process of installing my new in-dash DVD player. The problem I am running across right now is the pink parking switch wire coming out the back of the deck. It is suppose to be connected to the parking brake, or I have been told to just ground it so I can watch DVD's while driving. One of the issues is that I DO NOT have a parking brake. A while ago my Torque arm broke and ground off all my cables, so I just took it out since it was broken anyways. I have tried numerous different ground points for that pink wire and it continues to not work at all. I know for sure it is currently hooked up to a very strong ground point. How can I get the DVD's to play?? My car is a 95 Z28 and the Deck is a Jensen VM9311 DVD.95 Camaro Z28 LT1

 it's illegal and unsafe to do that.  Hook it up the way the directions read....even though you say you don't have an emergency brake.  somebody help me please

. This was done so that people do not just ground it so that they can use the dvd player while in motion, that is an unsafe practice and is illegal in most states. 2008 Scion xB
