i oreder stock foglights for my 05 2.5rs but it didnt come with a switch i found the wire harnes inside the car in the dash. there is 5 wires there black, red,yellow,purple, and i think blue but there is no power going to either of them and i was going to put in a switch that i have laying around does anyone know why there is no power going to the harnes.... thanks

Did you have your headlights on when you checked for power? Factory fogs only come on with the headlights, I've never looked at a wiring diagram, but I wouldn't be suprised if the switch only gets power with the headlights on. (and the key on)

thanks for the diagram but if i dont have the factory switch you think i can just grab to red and green wire as power and the black and white run that to the relay????
