ok, i pulled off the vent and took a look at the threaded hole you were talking about savy, i think that that is where the 2003 model bracket attaches for the fog light. i also took a quick peak under the dashboard where the switch for the fog lights is on the 2003. it looks to me like the wiring for the switch is already there to. i am going to have to look around some more but i am willing to bet that the fog lights will swap right over. so, if anyone wants to give up their fog light system just give me a holler and i'll take it off your hands.
