I saw you gave another curious person some info on a 2004 Chevy Cavalier (http://www.justanswer.com/chevy/39hsl-chevy-colors-tail-light-brake-light-turn-signal-wires.html)
I have a 2004 and hooked up a CANBUS error eliminating resistor to the dark green (right rear turn signal
) wire. When I did this, my turn signal stopped working entirely. In order to resolve that issue, I took the resistor out of the circuit and twisted the green wire back together (sealed with electrical tape to prevent a short).
When I turned my car on and tested the turn signal, either the bulb or the light socket/connector for the light started smoking!
I immediately turned the power off to the vehicle and replaced the connector (had the original laying around, just replaced the connector). I then replaced the bulb with the original (working when pulled out) in case the bulb had been blown during the possible short.
Now, however, the brake light and turn signal are both not working.
I was curious about the dark green wire... Where does it run? Is there a separate wiring harness for the rear power equipment? If so, where do I find it? I'm planning on doing a continuity test and verify the wire is still live with a multimeter, but I'd really like to find the other end of the wire before proceeding.
