Broken wiring harness

I broke the wiring harness that goes into the back of the car stereo and am not sure where to find a new one. I looked through the manual and there is no parts list or manufacturer phone number. Any ideas? Thanks!

Did I short out my kenwood in-car stereo?

To be honest if you have taken it apart then it is fried and the circuit board is not easy to replace i recommend a new radio, next time run your usb wire loose as you can so it wont never snag

Whats colors go to which?

  • Connect each wire yourself if your were unable to obtain a wiring harness to install your car stereo.

  • 2

    Connect the positive wire from each speaker to the positive connector on the back of the stereo first. Then connect the negative wire from each speaker to the negative connector on the back of the stereo. If there is only one wire coming from the speakers, the speakers are grounded at the chassis. In this case you will need to install new speaker wiring.

  • 3

    Connect the ground (-/black) wire of the stereo to a screw or bolt near where the radio is mounted in the dash. Make sure the wire is attached to metal, not plastic or fiberglass.

  • 4

    Connect the 12 constant and ignition power wires (both +/red) to the new stereo. Refer to your stereo's installation manual to make sure these go to the correct places.

    Im trying to find where i can gt a complete guide on how to install a car stereo from color coding the wires to installing a dash kit

    2. For an old stock stereo, you may have to remove the dash or certain parts of it to access the stereo. Do that by locating screws and bolts and taking them off. Make sure to keep them in a safe place.
    3. For an aftermarket stereo, insert DIN tools into each slot on the stereo behind the faceplate. Slide the whole stereo out.
    4. Disconnect the antenna wiring (The wire with the big metal tip)and the stereo head unit wiring (wire harness).
    5. Reconnect the antenna into your new stereo.
    6. Use **** connectors and wire crimps to connect the stock wire harness with a car specific one that is sold seperately. The color of the wires on each harnass should match up.
    7. Reconnect the negative terminal on your battery and see if it works.
    8. Slide the stereo back into the dash and remount the dash that you removed, including screws and bolts.
    hope this will help you

    Stereo turns off when headlights turned on

    Sounds like you have the ground for the radio hooked up to the illumination ground wire. Check for orange or orange/black wire coming from the radio harness. Did you buy the harness for the car as well? If so then just match all the colors of wires from the car harness and the radio harness. By car harness I mean the harness that plugs into the harness that the original factory radio plugged in to.

    Replacing a stereo into a 2005 Saturn Ion

    not sure if your still looking for a solution or not but here you go. that orange and white wire is normally the wire that controls the dimmer within the stereo. when you dim the dash light the factory radio lights dim and that wire is suppose to make the new radio do that also. in my past i have found that only about 30 percent of the aftermarket radios actually do that when hooked up. give this a try and let me know. good luck
