    Exclamation Cut off Stereo Wiring Harness

    Ok so about 3 years ago when I first bought my car I decided to upgrade the stereo system. The wiring harness was a bit difficult to find so in all my wisdom I decided to cut the wiring harness off and wire to piece by piece. That was a huge mistake. I drove around for about a week with no interior lighting or blinker usage. Finally broke down and took my car to a professional who wired it wire by wire.

    Want to upgrade headunit myself. Where can I find a wiring diagram of the speaker system on a 01 Elantra?

    you can go to hmaservice.com but you will have to do a lot of deciphering. i have a pic i took off of there and added the names of the wire colors next to each pin description:



    the problem you will have is that there are several wires that use the same color, and without the plug on the end to distinguish them, you will have to be very careful in determining which is which. so BE CAREFUL. notice there are several black, orange, and yellow wires. one yellow wire is ACC power and the other is a speaker wire. you can damage things royally if you choose the wrong wires. best thing is to use a multimeter to determine which wires of the same color do what.

    most suppliers of aftermarket stereo harnesses also make the reverse harness (the one that plugs into the stereo), making your cut harness essentially stock again. i know that you can get one from installer.com for $14. part # 71-7301.

    Luckily after I had my stereo installed everything was back to normal. Thanks alot for that reverse harness SouthPaw. Looks like that would make it a little bit easier trying to install a new stereo(beats the 80 bucks for an install).

    I got a adapter that plugs into the factory audio harness and into the stereo unit. This makes life much easier. If I decide to change decks, that is an easier swap. Using the factory deck later is just as easy as plugging everything in.

    I too cut my stock harness out before I knew anything about installing. I had to take the car to Best Buy and I threw one of the guys $20 bucks to wire it up for me. But luckily, I kept the stock harness in the armrest compartment for some reason. So when I learned how to wire up systems and radios, I was able to put my stock harness back together and bought the conversion harness that just plugs right into it when I upgraded to a better aftermarket radio. So now if I ever change radios again, I don't have to figure out what's what!
