Re: Foot well lighting!
Mine are wired into the head unit in the radio. Spliced into the line that comes on with the ignition. That line is spliced into the blue accents under the radio. And one of those accents is wired to the switch which is then wired to the foot well lights. A little confusing to figure out at first, but because it's all behind the radio, it looks clean. I was gonna go the same route as you (with the headlights) but I was intimidated by the thought of pulling apart my car looking for an existing hole in the firewall, or worse, making a new one. The purpose of the switch was in case I was driving around a bunch of cops. I'm pretty sure they're legal, but I don't want police hassle in case I'm wrong or they don't know I'm right.
