I'm hoping someone can help me out. I'm trying to ground the e brake wire so my passenger is able to view dvd's while the car is in motion. I'm not very tech savy and need some help locating the correct wire to ground. I understand its light green but i am still unable to find it under the dash. Any thoughts or comments would be greatly appreciated!!!

Re: DNX 7100 E brake over ride wire?
In your install manual, it'll tell you which wire in the harness of the DVD player is the e-brake wire. Simply run that to any screw under the dash that is screwed into metal framework. If it is in the plastic parts of the dash, it won't work. Find a screw that threads into metal, put a ring terminal on the wire, put the screw/bolt through it, and tighten it down, and you're done.

There is a wire that you are supposed to hook up to your emergency brake or another source to let it know your are parked. That same wire usually relies on a ground. I just grounded mine to a good ground under the dash and it worked great. Hope this helps and good luck!
There should be an option on your head unit to turn safe mode off. If this fails, you need to trace the parking brake wire that runs from your head unit back to the parking brake switch and disconnect it. This is illegal in some contries and therefore not recommended.
well to start the e-brake will need to be applied to allow you to see the video if it was installed correctly.................to over ride this feature you need a toggle switch with 3 pins on it
on the toggle switch there should be two logos (power & ground) if you run a small wire from the red wire from the back of your in-dash system to the toggle switch (power) and do the same for the black wire (ground wire)..........the last pin on toggle switch you attach the e-brake wire from the back of your in-dash system to the toggle switch pin and turn it on video will play
if this doesn't work switch the e-brake and ground wire around on the toggle switch
hope this helped
What type of car is it? Make sure the Black (Ground) lead for the radio is connected to an adequate ground wire in the harness or to chassis metal. Some vehicles (Nissan, Mitsubishi) have no ground lead in their harnesses and need to be grounded to bare metal.
The pink wire in most instances is the DVD's sensor that the vehicle is not in motion and is parked. It then allows the DVD player to display the movie not the warning message nor the blue screen. Your description "...pink wire on a bolt attached to the body..." indicates that said wire is constantly grounded. The DVD then cannot sense that the vehicle was parked. What this tell us is that the pink wire must first have a +12VDC before it is grounded. This changeover from + to 0 is the trigger. What is required is to have a single pole double throw switch. One end terminal is wired to ACC B+12 while the other to ground with the center terminal to the pink wire. Moving the switch from position OFF to ON (+12 to GND) simulates the parking brakes condition and will enable DVD playback.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
If it is shutting off and coming right back on I would defintley take another look at your ground connection. This is the most likley cause for the sudden turn offs. Especially if it comes right back on.
If your getting the "Can't view dvd in drivers view must apply parking brake" you need to recheck your ground. You might want to try another location for the ground. If the unit is VM9410 you can simply ground the parking brake wire and you'll be good to go.
