Is it possible to get the factory controller installed? For modern vehicles they may interact with some of the stability control features of the truck and/or even help control sway.
We called two Ford dealers. One never called us back and the other was no help at all. We found a place that specializes in all manner of hitch installations and towing. They have a “basic” brake controller but sounded very knowledgeable. They’ll install a brake controller that we bring in.
I would try calling the dealer parts department. I know for the new Ranger they have a controller they sell. Not sure about any year of F-150, but I don't know why they wouldn't.
I had that done on my F-150 about about 2 months ago, chose to buy and get it done at the Ford dealership because I believe only they can set the parameters and set your rear view back up system to coordinate with your trailer management system. It didn't take them long to install and had some peace of mind hoping as Ford technicians they knew what and how to install. They did good and all works well
Definitely get the Ford OEM controller. it will cost you around $100 from online dealer or E bay. It is very easy to install and activate. You will need to get this
