Expert Reply:
The Tow Package Vehicle Wiring Harness with 7-Way Trailer Connector, part number, # 118247, will plug inline with your existing wiring harness and provide you with the necessary wiring and 7-way connector to install a brake controller. The fuses and relays needed to install the harness are included to make the necessary brake and auxiliary power functions functional. You can retain the 4-way trailer connector and plug the new harness inline with it or remove the 4-way harness if it is no longer needed.
If you need a brake controller the Tekonsha Brake Controller # 90885. You can install it using wiring Harness # 3035-P, an adapter that is specific to your truck. The P2 is very easy to use and provides smooth braking
I will also include a copy of the instructions for the P2 for you to look over, as well as an installation video showing the controller being installed on a 2001 F-150. Simply click on the links below to see the instructions and the video.
