Well i pulled the switch out and followed the wires witch went to engine bay. Looks like it was for fog lights or something, so i pulled the wires out.
Nah not looking for a system yet, only bought this car to drive while i fix my Celica.
I figured it out, its to activate the NOS lmao. Tomorrow i will pull it out and see where the wires lead too. I really didnt think it was aftermarket. And also when i switch it on the switch lights up so its obviously getting power
