Hey guys, i have an SR5 with no fog lights, so i bought a set of factory lights off the internet, got them the other day popped out the covers in the bumper and popped them right in, I bought a universal wiring kit for fog lights at auto zone but when i was putting the lights in i saw that it had been PREWIRED for fog lights, so i just plugged them up.........BUT no lights??!! Is there some other thing i have to connect or is a switch needed?? I checked the fuses there is already a Fog light fuse installed and its good so what am i missing here to get these things going? ANY HELP or advice would be GREATLY APPRECIATED!!!
