how should I hook up my new HID Fog lights I don't want to drill into my interior for a switch so I quess hook to low beams is the best but how do I get the headlight out to get to it or does anybody know which is the power wire color for the passenger side low beam.

you don't need to drill into your interior... run the wire through the engine bay, and look for a small spot in the firewall where all the other wires go through. Cut off the switch, and slide the wires through there. Then just reconnect the switch and you're ready to go. I wouldn't tap into the other headlights, I would wire it to a fuse, or if it has a fuse inline already, you can wire it to the battery.
