What is this toggle switch for?

Is it an OEM switch and if so what option or option group? Is it for the courtesy lighting I think my car came with but see no evidence of the light near the kick panel on the passenger side. I am in the process of removing a hacked up wiring harness to install a new used one and my current harness has a toggle switch like it but its dangling from under the dash like about 10 other wires that are cut and connected to nothing. 32904922_45553359547900_Orig.jpg
