In mine (the one LIV1S refers to in the third post) the switch is a signless one, and I can't even remember it was hooked up when I got the car (that same picture was taken on the way home the day I bought the car). I later used it as a switch for indeed a fog light, a light I installed myself - no holes anywhere to be found, that possibly could be meant for that purpose...
Gonna remove that fog light again btw
