This truck has a 7 prong round plug for the trailer. Do I have to buy a brake booster for this year, or is the brake booster built in to work automatic when I tow a trailer?
vnm gave you the straight story on this. If you hunt through the glove box and the truck you might find the connector that came with the truck. All you should have to do is make good connections from the brake controller to the connector and plug it in.
I have a 99 F150 XLT 5.4L Supercab. I tow a 18 foot flatbed with it. The truck came with the towing package but it didn't have a brake controller. I bought a controller at WalMart then I went to my local parts store and bought the pigtail that plugs the controller into the trucks wiring harness (there's a plug under the dash just to the right of the steering column) and I had brakes on my trailer. Your truck is newer so I would go to my local dealer and ask them to check it, they can tell you if it has a brake controller or not or, if you can't get to a dealer, call one and ask what a brake controller looks like and where it's located then go check your truck yourself.
it doesn't have the electric brake box from the factory. you have to add it, there is an open connector under the dash, to the right of the steering column, i think gray 6 pin, to connect to a brake box. the truck should have come with a harness to splice to a box and plug in under the dash as i described. if it didn't, you can get one at a ford dealer
