Electrical connectors in trunk, 12V

[Litlsonic]

I am recently a proud owner of an early 2013 Model S. Got the jumper seats in the trunk and wanted to add some USB ports in the back for charging. Trying to locate a 12V line I can tap into and noticed a bunch of lonely connectors. Anybody know what these are for and if I can retrofit anything here? These are in the driver-side trunk side-panel.

On the passenger side is a wire harness that feeds the hatch power. Do a search and use a multi-meter to find out which two wires are our 12v constant and your ground and you can tap into those for lower power needs.

Thanks Ostrichsak. I was just wondering what those wire harnesses are for and if I can retrofit something. For instance, I don't have rear proximity sensors so one might be for that.
