What I did was: plugged in the harness into the fog light. Then took the trunk panels (inside) off so that I could see the frame, which exposed a couple wiring harnesses. The light orange wire is the one that went to the fog light plug, and the green wire (i think, im not remembering very well) went to turn on the taillights when the brake is presssed. So I spliced those wires together, and that was it.

Now my fog light turns on everytime i hit the brakes.
