I just put fog lights on my 03 tundra, they did not come stock. The truck was pre-wired for lights, I hooked up the lights and switch and bought the missing relay. I thought that I had everything I needed, and checked the fuse in the main fuse box in the engine. No dice the lights dont work! The bulbs and fuses look good and the switch in the cab lights up with the head lights. Any ideas?
