Doesn't look like a Factory installed switch, does it have any auxiliary lights installed?

That's an aftermarket aux lighting switch. I have the exact same switch in the same location (I installed- mine is red) for my KC floodlights. The red switch I have came with the floods.
I placed my switch in this location because of its relative proximity to the floods, which I mounted on the A-pillars.
There is a lot of room behind that speaker panel, so you should be able to trace the wiring coming from the switch to some end.
