According to the 2005 300 Series & Magnum service manual Fuse #16 is a 20A and supplies the rear power outlet of the LX49 model, or station wagon.
Sedans are equipped with two 12–volt electrical outlets. Wagons are equipped with three 12–volt electrical outlets.
The outlets are located in the following locations:
Cargo area right quarter trim panel (wagons only).
Inside the center console.
Next to the ash receiver in the center stack.
The outlets in the console and quarter trim panel have power at all times, and include tethered covers. The outlet
in the ash receiver tray is shipped with power available only when the ignition is in the ON position. This outlet can
be changed to provide power at all times by moving a fuse in the fuse block."
So, what you are missing is only the Dodge Magnum. Good luck finding it!!
