Extra electrical connector

[A. Ise]

There is an unused electrical connector on my 2013 Ford Edge SE and I'm hoping it is some kind of connector for trailer plug. It is in the cargo area on the passenger side behind all the plastic sort of behind the tail light.

Audio amplifier connector?

 

Here's how one company adds trailer wiring (FYI). https://www.etrailer.com/tv-install-trailer-wiring-2014-ford-edge-118515.aspx
