Passenger A-pillar Plug?

[C6H12O6]

Stumped. Been searching and looking in the wiring diagram book, but can't figure out what the heck this is. I pulled the a-pillar cover off the passenger side to run a wire for my recent HAM radio install and found this hanging there. Anybody know what this is?

@hoser @spressomon may know. Their knowledge is scary.

Thought it was some aftermarket something or other, but looking at the install, it seems pretty legit—factory-like plastic frames to attach to the pillar, intricate tape and shrink tube... way too clean to be some hacker aftermarket shop. Seems like a data port of some sort.

I had my a pillar trim off of my 2002 about a month ago and definitely did not have that connector. My guess since you have a newer cruiser would be something to do with overhead DVD player?

Which I don't have. Thought that might be a possibility. Looks like that sort of plug. The NAV screen option for rear video is greyed out, so maybe it is pre-wired at the factory for a port-installed option to put in the overhead player. Interesting possibility.
