My '08 LS didn't come with fog lights and I need to replace the bumper cover anyway so I got a cover for an LT model with fog lights. They are like $50 cheaper to boot. I got a pair of fog lights off Ebay and bought the mounting grilles from the dealer. How can I wire them up? I don't see any factory wiring harness that I could plug them into. I was hoping to just buy a factory headlight switch with the fog light mode and just plug everything together.
