Wiring Harness Two of my wires have been pulled out the harness for my jvc kd-g210 stereo. One of the wires is the yellow battery wire and the other is the purple positive right rear speaker wire. Can i replace the wires with another that have similar or the same characteristics. If so, at which points in the harness are they positioned?

Car's wire harness color may not be the same as Radio. Best option is to buy an adapter from ebay. Cost on a few bucks.

Check fuses and double check wires

The yellow wire is the constant 12+V.
It has to be hooked up to a constant battery source.
If you did not install an aftermarket wiring harness consult
http://www.installdr.com/QuickWiring.html to find the constant 12+V wire color code in your dash.
If you unhook your battery, you can splice into the cigarette lighter hot wire to keep the constant memory of stations and clock time.

Connect Yellow to Battery (always 12V), red to ignition, and black to ground. Disconnect all others. Check it. If the radio stays on and plays CD, then radio is good. You may check other wiring

First you need to get a wire harness for the Chevy (check Ebay) then follow the wiring instruction inside the package on how to join the spliced wires togother. After joining the wires togother plug the harness in and stuck the JVC into the recess where the old stereo was and thats it, it should play if not you don`t have a good ground, ground the body to the frame.

have you pulled the deck and checked the built in fuse beside where wiring harness plugs in

I would need further information: What most people do not realize is that a wiring harness is not a "one size fits all" thing. There are two harnesses that you may need.

To remove your factory car stereo and install a new aftermarket car stereo there are wiring harnesses for most cars that will plug right in to the wires from your old factory radio.
For that, you will need to buy the correct wiring harness for the year and make of your vehicle. Say, for example: 1987 Toyota.

Then there is a wiring harness for the specific car stereo. You will need the make and model number of the unit itself. Example: JVC model KD-AVX77.

Hello james_sweet,

You can purchase a wiring harness here for your JVC prewired with a plug for most vehicles.

Hope this helps.

Most stereo manufacturers agreed on a color-coding scheme for their wiring to keep things consistent. In that scheme, red wires are run to power (ie, the battery) and serve as the ignition-switched power leads (so when the engine is shut off, the head unit also shuts off), black wires are grounds, and purple, gray, green, and white are used for the main four speakers. Blue is an antenna and/or amplifier turn-on wire. Orange is a dimmer wire (for cars with dimmers on the dash lights, this can be tapped in to also dim the head unit's lighting). Yellow wires are typically the memory wires. These feed power to the head unit constantly, regardless of whether the car is on or not, so that memory presets and tone settings are maintained. Your JVC unit should have a yellow wire coming off the back as part of the harness - this would be the one to supply power. You can run this directly to the battery - that way if you blow the fuse in the fuse box that you're considering using, you won't lose your stereo settings as well as whatever feature the fuse was utilized to protect.
