so I took apart the back of my car to clean the sunroof tubes, and found this plug. it is on the passenger side rear, right where the cargo area light is, and it was clipped to the back side of the support. 2 wires, one red/blue, one black. I scoured the fsm for this but obvoiously am looking in the wrong place. anyone know what it is?

 

The plug is for your license plate lights. It passes through the grommet and is behind the rear bumper cover.

 

thanks
