You asked about my fog lights, I got the lights from LMC Truck, wiring harness from Advance Auto, it wasn't wired from the factory, switch from the dealer. Cost bout 200 for everything. Also got an extra headlight connector from dealer. Needed that for the extra wires. Took me about 4 hours I guess. Really didn't time it. They come on with the low beams, parking lights, and high beams.
