If you have the factory 4-way, then you simply need the Replacement OEM Wiring Harness for Ford F-150 # C56110. If you have the factory 7-way then I recommend the Reese Multi-Plug Wiring Harness for Factory Tow Package - 7-Way and 4-Way Flat Trailer Connectors # 74682. Your truck will have either the rectangular connector or the round connector already present.

These will simply plug into the factory wiring which is present even without tow package and you will be good to go.
