No Picture when playing dvds

[Drifter]

I have recently purchased head unit with dvd player. I installed It a few days ago

without any problems(or so I thought) upon putting a dvd in I noticed that I did

not have a picture on screen at this point I went over my wiring harness and come

across a wire not hooked up to anything the wire is labled like like this (B-) brake

screen safety trigger wire also on screen it says the same thing. Can someone plz

help me out here? What is this wire and where do I tie it into so my DVD player will

function proberly? Any help is appreciated.

Just ground those wires. You'll be watching dvd's in no time. Then... don't kill anyone please.

It is a Nesa model NSD-438

Is there any certain area that it should be grounded to? And no worries I will keep my eyes on the road!!
