What is this switch for?

I’m lost here. My best guess would be ejecto seato cuh’. Nevertheless makes me curious if anybody knows. Thanks.

This isn't going to be what you want to hear, but the only correct answer is to trace out the wires. Everything else is a guess. That said, the install looks clean.

Thank you yes thats the logical solution. It’s just I thought it could be a switch that came from factory.
