    Does anyone know the purpose of the blue connector behind the rear air vents?
    It is taped to the harness that also connects the rear USB ports. The air vent assembly pops off easily by the way, at least on my car.

    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.
