Mystery switch. And fog lights.
 

I have a 1995 Montero SR and there is a factory looking toggle switch mounted just to the left of the data link connector. Does anyone know what this switch is? Doesn't do anything noticeable in either position but I'm sure it has a purpose. Also does anyone know where the fog/driving light fuse is? There is no mention of fog lights even existing in the owners manual or fsm that I have been able to find.
