what's this harness for?

[Wills05xlt4x4]

The two on the left are light controls... What's the one on the right? It's plugged into a cap that just covers it...
any help would be much appreciated.
thanks again guys,
Will

Possibly wiring for the adjustable pedals or reverse sensing system.

I have the adjustable pedals(other side of wheel) so it must be for the backup sensor stuff...

It is for the reverse sensing system. It's pretty easy to add on, if you're interested. If I'm not mistaken, all of the wiring is in place. You just need the sensors, trim piece for the bumper that holds the sensors, the module, and the on/off switch.
