Open connecter in trunk area

[Ssmtsx]

Anyone know what this connector might be for? Only thing I can think of is maybe it’s for the factory hitch wiring? It’s right behind the buttons to fold the back seats over

I don't think this would be used for the tow hitch, as if I remember may be from watching Sandy Munro recent Model Y video,
I think there is already a plug that could used for the to tow hitch harness located behind the rear bumper cover.

So my assumption would be a harness that could be used for the third row seats
to provide heating and to detect if a passenger is not wearing a seat belt?
Since there are height pins, this could be a good possibility.
