Question:
I have a 2015 F-150 without tow package. It does have factory 4-flat connector at the rear bumper. Do you sell a plug and play part that will allow me to add a 7-pin connector at the back? Im hoping that I can simply unplug the 4-flat and plug the 7-pin into that connector. Let me know if Im mistaken. Thanks!

I wish there was a simple plug-in option for installing a 7-way on your 2015 Ford F-150 but there isn't at this time.
Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way.
If you do have trailer brakes you would need the # 37185 as well as the an install harness for the brake controller like the part # 22292. There are a few connections at the rear of your truck that you would need to make as well. The brake output circuit will be ran to the rear frame rail that you will need to run to the 7-way. I attached a picture that shows the wiring as well as an install help article for you to check out.
For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.
