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?
