Re: Memory Back up wire on wiring harness, what will it...

It needs to be connected to any source that has power while the vehicle is off.

Cigarette lighter on most American Cars is always on, otherwise, the headlight, taillights, or dome light would suffice.

Best of Luck.

Kenwood deck kdc-mp2035 im not sure about blue wire or yellow or red

Normally on Kenwood, blue is not usually used, it's for power antennae, make sure it's end is not bare though. Yellow would be to a continuous 12volt+, for memory. Red goes to accessory, (+12volt) where only power when key on, or in accessory position.

Where do you connect the memory wire on a jvc kd g110 car stero.....what color is the memory wire ?? what does hook red wire to acc fuse mean??? what wire does the red wire on the radio connect to on...

The yellow wire is most likely the memory wire as it needs to be connected to a constant 12 volt source.

"Hook red wire to to acc fuse" means you need to hook into the fuse block under an Accessory Fuse. (ie: something that can't be turned on unless the car is running or the key is in the "Accessory" position)

The red wire is explained above. It does not connect to the harness.

Just remember that the yellow wire needs to be hooked to a constant 12 volts and the red needs to be hooked to a circuit that is only active when the car is running or switched to the "ACC" position.

I need to know the wiring dia

all your wiring is color coated. if you have your harness from the the new reciever and you have purchased an adaptor harness which plugs into the vehicles existing harness enableling you to wire every thing as it is color coated you have red wire a yellow wire a black wire. your red and yellow are power and your black is your ground wire .your red should be be your acc or ignition wire which gives you power to the unit when the ignition is on should tie directly to the red wire on your adaptor harness, the yellow is your constant 12 volts which is for memory and keep your presest along with your time and features such as that it will tie with the yellow on the harness as well then the black is your ground the unit and will tie with the black wire on the harness. that takes care with powering the unit next you have a set of wires that you will be using to tie your sound to they are color coated as well and will tie to the new harness your front left and front right channels are white/white and black and usually gray/w a gray and white for the right channel thats your front. your rear is green/w green and purple and purple/w purple and white stripe for the rear speakers i hope that helps you out a bit

Problems with Metra METRA PR01-0001 PIONEER 16-PIN UNIVERSAL WIRING HARNESS?which wires are which

I don't know what pins are what on the METRA harness, but the wires coming from the back of the Pioneer unit should be:

black ground
red accessory (KEY)
yellow memory constant power,
blue is remote,
orange is for the dimmer,
green with black is left rear neg.and green is positive,
violet black is right rear negative and violet is positive,
white is left front positive and white with black is negative,
gray black is right front negative and gray is positive.

If you don't have the pioneer harness (and so these wire colors dont' mean much to you) just message back here, and I'll map those wire colors to pin positions on the back of the unit.

I cant get power is my harness missing wires?

Yes, your red wire is for ignition, yellow wire is for battery and black is ground. The red ignition wire is for the radio to turn off and on with the ignition. The yellow is always hot, for memory.
