Parking brake bypass?

[clos69]

I just bought a dvd player(VR3 brand with a built in 3in lcd screen),and i can not get it to play the dvds.I get an error message that reads -Parking brake..........I looked at the owner's manual and there is a wire from the reciever that i need to connect to the -neg wire on the parking brake.. anyone here know how I can bypass the problem and get the unit to play the dvds on my 69? thanks
