If you don't mind some extra work, you can wire the front fog lamps to operate with the rear fog light, thus avoiding the dreaded dealer visit (and departure of excessive $$$ from your wallet). That's how I installed mine. A bonus of this approach is the nice indicator in the instrument panel display when your fog lights are on. There is no similar indicator when operated with the new front foglamp switch, except a small LED in the switch itself.
This involves rumming a wire from the rear fog lamp socket to a location under the dash, relatively easy if you remove he door sill moldings (they just pull off after warming with a heat gun or hair dryer).
