For your 2016 Ford F-150 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 and the install harness part # 22292. If you check out the install video I attached you will see how the connections would be made.

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.

I can't recommend the # HM40975 as a fit as it would not wire up properly to your vehicle since it doesn't have the needed harness and that's not something we carry.
