If you don't have power on the left hand stop/turn signal pin on the trailer connector for your 2006 Ford F-150 then you likely either have a blown fuse or a loose/severed wire. The fuse for this circuit is located in the engine bay fuse box, slot 42 which is a 10 amp fuse. If this fuse is good then check the wires at the back of the trailer connector and work your way back to see if any breaks are present.

If you still can't find anything wrong then you may just need to replace the factory harness with the Plug-N-Tow Vehicle Wiring Harness part # 40185.
