Unused harness connector behind rear air vent assembly

hard to tell how many wires are there from your picture, but my guess would be data connections for the usb ports?
Looks like a 3 pin connector. Not useful for connecting USB data (unless you only connected a single port - possible if there was a built in hub between this connector and the ports in the vent assembly) and only if you are grounding elsewhere with a shared ground.
Or it could be a 2 pin connector in which case it's probably totally useless for USB data ... unless the vent assembly is providing ground AND power which would be even stranger.

It could be used for connecting a thermistor to control the temperature of the rear passengers vent?
But possibly this didn't get implemented.

Oh that wire was for rear fan control. At some point there was a prototype with a physical rear air button, and while the button was removed, the harness wasn't changed.

So the wire wouldn't even show on a diagram. Wonder what it's hooked to. Perhaps that's how they get sound for the external speaker on the newer models
Hmm …. Curious what the signaling would be for it.
I’m sure I could find a decent looking +/- button, and Mouser carries practically every connector known to man ……

It's meant for an illuminated button........
Pin 1 = High Side driver for Button signal &LED
Pin 2 = Ground Return
I've been tempted to hook it up myself - did they leave the code in for it to work if it's connected? Probably not.... but..... always curious!
