Mysterious unused electrical connector

[CKTofu]

Hey guys. I have a 2009 Aveo LT Notchback, and there's an electrical connector in the trunk that I have no idea what it is for. I'll link to some pictures I took, but I can't think of what it would be for, unless one of my speakers aren't connected. Any ideas?

EDIT: All my speakers in that area are connected, and with a different style of connectors, so now I have no idea. The trunk light is connected and working, so it can't be that, either.
