If there is a factory 7 pin connector is there a brake controller already?

I have a 2004 explorer which I am the second owner. I have the original window sticker and it has an additional option listed at class III/IV tow package for $400. On the rear there is a 2 inch receiver and a capped 7 prong connector.

I am new to looking at trailers and to understanding TVs as well. Does this 7 prong connection means that the brake control would work or just the brake lights?

Thanks for the help.

This is a 6 cylinder and althougt the car is rated to tow over 5k I would only use it to pickup a dry trailer up to 4k. But it would be nice to know if the brakes would work on the trailer as that would certainly extend my interest in towing beyond a few flat miles.

You have to have a separate brake controller installed in the truck to have brakes. Then the brakes should work with the wiring you have. Others? Jim

Thanks. Etrailer had some great resources. Turns out my explorer is pre wired and ready for a brake controller as is my wife's car. I think I will be placing an order for the controller shortly to be ready.

Any suggestions for a decent controller that could be swapped between vehicles? We would only have one car tow Mine is a 6 cylinder which would work in a pinch. Her car is much nicer and a bigger 8 cylinder so I think she may only use it to tow when the trailer is fully loaded. Was looking at the Tekonsha Prodigy P2 Is that a worthwhile unit?

I still use a Prodigy controller that I bought about 8 years ago. The closest thing to it on the Tekonsha website is the P2 I also bought a couple of spare mounting pockets. I use it on 3 different trucks with 5 different trailers ranging from single axle 3,000# up to a monster 3 axle goose neck with a GVW of 35,000#. It is easy to swap between trucks and takes less than a minute to get dialed in when I move it.

One thing to note on the Ford, you may have to add a relay in the fuse block under the hood for the brake controller. Also Ford has a whole separate set of fuses for the trailer wiring so they are independent of the tow vehicle lights.
