DVD head units have one extra wire in their wiring harnesses, compared to a standard CD head unit. On my Jensen, it's a peach-colored wire, and is the activation wire for the DVD feature. During the installation, the instructions call for this wire to be tapped into the emergency brake indicator light wire. The reason is this:

The e-brake indicator light is what is called a "ground complete" circuit. That means that the bulb always has power applied, but when you pull the brake, that puts a ground to the wire and completes the circuit, allowing it to illuminate. The head unit sees this ground, and activates the DVD player.

In my Jensen unit, I simply ran this wire to a ground (I used a screw near the fuse box), and I put a switch on the wire, so I could break the ground contact at will. Jensen calls for a procedure to activate DVD playback. In their instructions, they tell you to select DVD from the option menu, and when the "lawyer screen" comes up (the one warning you to park before you watch a movie), you release the e-brake for 3-5 seconds, and then reapply it. To simulate that with the switch I used, I leave the switch closed (activated), and select DVD. Then I flip the switch "off" for 3-5 seconds, and flip it back "on". This tricks the head unit into thinking I put the e-brake off for a few seconds and then put it back on, and the movie will start. Then I can drive away.

Basically, ground the wire that is used for DVD activation, and put a switch inline on it. Then you can break and reapply the ground in whatever manner is required by the manufacturer of your head unit. If there is no off/on sequence with yours, as there is with mine, simply ground the wire to a screw inside the dashboard and you're done.

Where does the pink praking brake wire go on 2003 cadillac deville go


Where are you seeing this pink wire ? I'm looking at a wiring diagram and I see a pink wire at the (RIM) rear integration module . It goes to the park brake relay A ,control side . The RIM supply's a ground on that circuit energizing the park brake relay A . There is another park brake relay - B . Are you familiar with the RIM module .
The park brake system is a mechanical and electrical system which operates on the rear disc brakes. The system is activated by depressing a foot pedal lever assembly, which sets the rear brake caliper via cables. The park brake is released by shifting the vehicle out of park or activating the manual release.

Park Brake Release
The rear integration module (RIM) controls the operation of the electric release park brake. The RIM uses serial data messages to determine if the correct conditions exist to release the park brake. The park brake is released under the following conditions:
• The engine is ON.
• The gear shift lever is not in Park or Neutral.
• The park brake switch is closed.
When all of the above conditions exist, the RIM releases the park brake by simultaneously activating the 2 park brake solenoids. After 2 seconds, the RIM deactivates solenoid A. The RIM continues to activate solenoid B while the above conditions exist, which prevents the park brake from being set.

There is no video on my kenwood ddx8017, why? Do i have to bypass the parking break wire? which one is it, the solid green, or red with black, or pink?


If you want to watch videos on your unit it is necessary to bypass the parking brake wire from the Kenwood unit. The parking brake wire is light green and the best possible way to bypass the unit is by installing a toggle switch. The toggle switch should be a two wire device. Connect one wire to ground and the other wire to the parking brake wire from the unit. This will allow you to switch the supply on the wire to ground when needed.
Also, in some older Kenwood units you could just as easily connect the parking brake wire to ground and be done with it but, it does not always work.

I have a jenson indash dvd player is there a way


most of the times this is solved by putting together the pink wire with the black ground wire and then to your chassis. some newer models require this to be done three times (stepping on the brakes three times before you get a signal). you can use a switch between this connection and turning it on and off three times to get the signal. you will have to repeat this everytime you turn off the unit.

Usually the wire should be grounded. Connect the wire to a ground point via a switch (is illegal to watch TV/DVD while you're driving)

Xo vision xod-1730 product showing no image?


to watch dvd video on xod1730 like what adamdog said you need to attach/mix the pink/braking wire to black/ground wire and if you want to disable the pink/braking wire all you have to do is not to attach it to black wire or any wire and cover pink end wire with electric tape.
