Looking at a new to me 2016 Rubi. It has the switch/ knob and I cannot figure out what it does. The led lights up when you press the know and the intensity changes as you rotate the know. What thinking it was some kind of sub woofer control but there is no aftermarket stereo stuff.

Jeep looks like it was setup as a rock crawler with full hydraulic steering, but no remote for the shocks.

Any ideas?

 

Wow. That's an interesting setup. Have you tried tracing the wires? Could be just about anything.

 

I would take a wild guess and say that was for someone's aftermarket sub that was in it at one point.
