We all have it. It's an option on the sport model, and if your car doesn't have it, then the 3rd light is just a plastic cap. It'll cost about $200+ to get the fogs up there, or you can buy lower fogs for less than $150. Your choice.
on the integrated fog lights, it doesn't have a actual "switch" but on the lever where you turn your lights on, there is another thing to turn in the same direction of the headlights. if you don't have that than you dont have the fog lights. it would help if you told us what model 6 you have
