wire in closet?

We just purchase a 2012 Bighorn 3670 which was manufactured 10/03/2011. In the closet next to the antenna booster is a wire with a five pin plug on the end which extends from the closet wall. Wondering if anyone knows what this wire is used for?

Power lead for a roof mounted satellite dish.

Right on the money, it is prewired that way, in case you ever want to add a Sat. system.
