I've got a 2011 Supercab XLT. I've added a wireless back up camera and have mounted the monitor in the space where the factory brake controller is located (has a small cubby there instead). When removing the panel to remove the cubby and mount my monitor I discovered a small female harness plug. It was "plugged" into the round coin holder.

What does this connect too? More importantly, is it something I can tap into to provide power to my monitor (don't want to use the cig adaptor)?

It was plugged into the back of the coin holder to the left of the radio.

 

Just use a 12v test light or volt meter and see if there is power there. Im sure the wires provide everything u need

It is the plug for the 4x4 switch. As suggested try a meter or light but I would be surprised if there wasnt 12V switched or constant power there.

 

The wiring harness is the same for most F150s and for options not selected the factory workers tuck away unneeded wiring. If you are not sure what you are doing I suggest going to a reputable stereo installer or dealership. Seen too many people blow fuses and the like when tinkering the wires.

 

Its for the integrated trailer brake controller. or its unused wiring for the 4x4 switch. but since ur 2wd its not used

Convert it to 4wd. All you need is a switch.

Thanks for all the feedback. Grabbed the meter we have at work and identified the hot wire and this is the result:
