What is this toggle switch for?

It says map light on the bezel, so it's for the map light! The bezel is seperate from the switch, and is held together by the but for the switch! There is a little pin on the back of the bezel that goes into a small hole to keep it from spinning!! The wires should be pink or yellow, which is the color for interior lighting! I can look at my schematic and check for sure!
