I tapped into the wires for the parking and signal lights in the headlamp wiring harness. You have to tap each side for the signal lights, but only driver side for the parking. I was hoping to trace all of the wiring back the fuse box and tap in there somewhere, but that proved to be too complicated. I accessed the headlamp wiring harnesses through the wheel wells, as explained by some others on the forum. Much easier than taking off the front.
