Had an 18 F150 with no factory brake controller. Bought a factory brake controller and that one pushed right into place against a connector.
Now the dealer will tell you that they have to perform a function so that the truck see’s the controller and the computer system will control it. If you’re comfortable with getting into your truck computer there is a simple way to do it yourself. I recommend doing some Google searches for UTube videos that will guide you on how to make bit changes. You’re going to need to download Forescan and pay a small amount to access the software to enable making the change. The only other device will be a cable which you can buy on Amazon for less than $30.
Ive got a 22 Timberline with the HD tow option so I don’t need to get into adding the brake controller. Something you need to know, there is likely a section of harness behind the dash where the controller connects to with a short harness section that should come with the controller or should be available ato be purchased. Again someone has probably created a UTube video.
one last thing to mention, FORScan can turn on options that are capable of running on your vehicle but have not been activated because you did not pay for that option.
