Using without parking break

Hi James,

Page 27 of the installation manual ( shows a connection to the parking brake light circuit. It is the Light Green wire labeled "PRK SW" shown below.


If it is connected the way it is drawn, the PRK SW wire is connected between the lamp and the switch that opens and closes depending on the position of the parking brake (set or not). 12 volts is always present from the battery to the top of the lamp. It passes thru the filament to the wire that goes the top of the parking brake switch. So, when the brake is OFF or disengaged, the lamp is off and 12 volts is present on the PRK SW wire to your Kenwood GPS. When you set the parking brake, the ground (symbol is the funny slanted lines under a horizontal line) just under the brake switch passes through the switch and changes voltage at the PRK SW to "ground" or 0 volts. When this happens, the ground on one side of the lamp with 12 volts on the other side of the lamp - make is turn on.

So, what does this mean? Simply tie the PRK SW wire to any grounded metal and the Kenwood will think the parking brake is always set - for as long as it is tied to ground. You can check it with a simple voltmeter to be sure. Set the meter to 12 volts or more, touch black lead to ground & the red lead to the PRK SW wire. Kenwood should only work when at 0 volts (brake set). Release the brake - meter shows 12 volts & the Kenwood shuts off.

I hope this helps & Good luck!

How do i by pass parking brake wire for indash dvd jensen vm9312 i'm puting it in old car no p.b.

Hi jason
To answer your question;
You do not need to connect that wire but you need to bypass the parking brake function in the menu.
Here`s the parking brake bypass procedure:
1: Go into AM/FM mode
2: Hit "setup" on the remote control

3: Enter 543210 on the remote, listening for the beep for each number
4: A new menu will appear. Touch the button that has the hammer/screwdriver on it in the upper left-hand part of the screen.

5: Select Brake bypass to "ON" and hit the "X" near the bottom of the screen.

6: Use the unit wisely and above all safely. A ticket is one thing, causing a fatal accident due to negligence is another.

Hope this help Cheers

How to by past the brakes wire for the dvd to play

According to the owner's manual, the pink wire is your parking brake wire and it has a label 'PRK SW' on it. It requires a negative signal to show that the parking brake is engaged. If it is currently hooked to your parking brake, you will need to trace it to where it is connected and remove it first. Be sure not to leave any wires exposed that can short out. Then connect the wire to a source of ground. this can be the black wire coming from the head unit, or a convenient screw nearby that is mounted to the vehicle chassis.

The manual can be found here:

Please note that it is likely illegal to have video playing where the driver is in view of it. Check your local laws before considering making this modification.

Question jensen vm 9512 put in pat code still getting cannot wash wille driving

You cannot watch while driving as it's a safety feature of in-car dvd players, to by pass, disconnect from handbrake/parking brake switch.(found at the base of handbrake/parking brake). But doing so makes the use illegal in most countries not to mention dangerous.

Bypass for video on a kenwood ddx-512 car dvd player

On the wiring harness there is a green parking sensor wire (PRK SW) that you have to hook up. All you have to do is ground that anywhere on the chassis of the car then youll be set.

How to by pass the jensen dvd player prk sw parking brake.

You have to hardwire it to bypass the e-brake. Take the peach-colored wire and ground it to metal inside the dash. Put a toggle switch inline on the wire and mount it somewhere you can reach it. When you get the blue screen when starting a movie, open the switch for 3-5 seconds, then close it again to reapply the ground. Your movie will start up, and you can then drive away with it playing.
