Using without parking break


Hi James,

Page 27 of the installation manual (http://www.wwstereo.com/_files/155788/documents/Kenwood--Manual.pdf) shows a connection to the parking brake light circuit. It is the Light Green wire labeled "PRK SW" shown below.

507e8abd-cbd0-4811-9c76-ad8a0f498b77.jpg


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!

My Kenwood DPX-4020 suddenly went "dead". No power whatsoever on the led's and nothing happens when i push any/all of the buttons. I have it reset many times, checked the wiring's and fuses at...


1st you need to check the fuse in the fuse panel in your car to see for some reason the radio fuse is not blown . if is change it . if not take your radio out and see if fuses for radio is blow on back of radio then some have a fuse on the red wire check fuse there too. if nothing buy a digital volt meter and start checking your ground wire to see if it broke . take volt meter turn on dc volts put black test lead on your radio ground then take the red test lead and and start touching the yellow wire to see if you get a 12 volts on meter if you get 12 volts ground is good ... then check the red wire turn on the ignition switch and put the red test lead on red wire and see if you get 12volts if nothing

either you have bad ground or you have a fuse blow in car some were .. if you can't figure it out call a local mecp certified shop and have them look at it ....

its possible that the radio is just died and you need to buy a new one electronics dont last forever when you use them daily ...

I am installing the DEH-3200 into an 06 dodge ram. I bought a scorsche adapter kit and I followed all the instructions, but I can't get any power to the stereo? Any suggestions?


if you have a digital volt meter check powers at radio to see if your getting a good ground ..

take the black test lead of the meter put it on the ground were you mounted ground wire. then take the positve red test lead and the touch the red wire on harness from radio to see if there is 12 volts

and the do the same for the yellow wire constant power must have 12 volts all so if you get nothing either its a bad ground or fuse is blow then check fuses if everything is good and no fuses or blow then the radio is bad ....

My memory wire is yellow & my power wir is red. I have them all hooked together so that the stereo will turn on. My kenwood cd player will not hold memory. Can you help??


The red wire goes to the ignition 12 volt source, and the yellow to the battery 12 volt source. The yellow wire must remain hot with the key out to retain memory.

Why wont my personal setting save for my Kenwood KDC-X493 car CD reciever? This is my 2nd aftermarket cd reciever and just like the 1st one I'm still having this problem.


Make sure you have the +12VDC and the Ignition leads hooked up properly.

If your head unit is pulling is power off of the IGN lead, it will reset every time you turn your car off.

I was wondering which wires are which to hook up an after market stereo in my 1991 plymouth laser. i need to know what are the power wires and the speaker wires on my stock wire harness.


I don't have the exact wire pinout, but I can offer you a generic method. Usually wires in an automotive wire harness that are Red, are power.
I would suggest you buy a cheap multimeter, (If you don't already have one), and set it to the DC volts-50 volt range. They have multimeter's that are relatively inexpensive. $10 or $12 dollars.

There will be a Red lead to a probe, (Positive), and a Black lead to a probe. (Negative) Hold the Red lead to the red wire. Touch the Black lead to any good ground. Any clean of paint, metal surface on the car. The needle should go up to 12 volts on the DC scale.

Ground wires are generally Black or Green. Should you see a Green wire with a stripe on it, this is not a ground wire.

Wires that are of a solid color and have a stripe on them, are usually speaker wires. They will be in pairs. There should be a wire of a solid color with a stripe on it, and a wire of the same color, but no stripe, to make up one pair. One pair is for one speaker. For example:
Blue color wire with a White stripe, and a solid Blue color wire.

There may be two pairs of wires, or four pairs. Two speakers in front, two speakers in back, for the four pairs of wires.
After you find the power wire, and have it attached to the stereo, plus a ground wire, I suggest you make sure ALL the other wire ends are not touching each other, on the stereo. Put a small piece of Black electrical tape on them.
Take one pair of speaker wires, from the car harness, and attach them to the stereo. Turn the stereo on, and see which speaker wires you have. Move the Front/Back, and Left/Right controls.
Now it's just a matter of finding out the correct hook ups for those wires. Match them up.

If there was no spark and wires hooked up wrong in the first place, your player should work if you find the PWR lead and the Remote lead and ground. Then speaker wires +) and (-
