2006 sle xl, disconnected wire?

[Tjames]

Hi to all, Just purchased a 06 Envoy and have been going over every inch to get to know the vehicle, while detailing the engine I noticed a wire just hanging there coming out of a wire bundle near the fuse box on the right side of the engine compartment. looks like it should be attached to the open screw on the left on the front of the fuse box. Can someone inform me what this wire is for (I was thinking hitch outlet power receptacle). I can get a picture if needed.

Thanks

144 views and no ideas, lol. Anyway thought I would post a reply to my own post for anyone in the future with the same question. The wire is the 12v feed for a trailer, normally disconnected unless needed. I electrical taped mine and put a label on it.
