2006 Tacoma 2TR-fe Mysterious Plug

I have a 2006 Tacoma with the 2TRFE and I have a mysterious plug behind the switch panel. I have no idea what this is for. I've tried scouring through wiring diagrams to no avail. Below is the image of the plug. I believe it was behind the top right switch blank but I moved it for aftermarket switches. If anyone has an answer that would be much appricitated.

 

Usually those connectors are for options that the truck didnt get. The reason they have the wiring is because its cheaper to have the same wiring harness for all of the trucks. If it was in the top right blank spot, I know in my truck that is the 400W bed outlet.

 

The one with the Grey/Black wire is for the Auto LSD Switch on trucks equipped with VSC which was a rare option in 06.
Fog Light Switch connector has Blue, White/Black, Green, & Green/White wires and is black in color.
