2 Wiring problem

Failure Date: 09/04/2013

I turned my car on and it immediately warned me that my left read brake lamp was not functioning. To be specific, there were four warning lights one for the reverse lights, one for the brake lamp, and two other ones. All for the left light. I opened it up and immediately observed that the wiring harness plug where the wiring meets the bulb holder had shorted at the ground wire. The two pieces were melded together, suggesting there may have been a small fire. Bits of melted plastic fell all over the place when I managed to finally pull out the plug.
