TMC is my main home for all things Tesla, but since I found the rough instructions on M3OC, I felt I should post my how-to guide in that thread. Here you go:
Not re-routing the existing hub; I'm adding a powered hub so I have ports for the 2 phone docks, a corded extension for my wife to use her phone (up close) while I drive, and 1 or 2 USB memory sticks. Before I had a USB adapter plugged into the 12V outlet and ran the wire under the trim on the side of the console. Routing it this way is a lot cleaner and frees up the 12V port for other stuff.
