I have a F-250 SD that I installed oem fog lights on, I also installed the OEM headlight switch for the fog lights, but the lights still dont work, ... Yes i checked the fuses, yes I checked the bulbs, the fog light harness is plugged into the factory harness... So it seems to me that I am missing a relay somewhere... does anyone know where the relay is located...

Thanks

John
