I pulled out the coin holder that is to the left of the radio today and attached to the back was a harness with 4 or 5 wires going back into the dash. The plug doesnt go to anything just the back of the coin holder. What does this go to?

 

In 4X4 trucks, that's where the switch would be to engage either 2WD, 4H, and 4L. In everyone else's, we get this cool (useless) little coin holder lol

 

There's a harness and wires coming off of it? I have the same useless coin holder..
