Travel Trailer questions.? - open road travel trailer 2004

I bought a mobile home through a private sale, and although my tractor came with factory tow package, they said they had not received an electric brake controller, and brake friction stabilizers. Can someone explain what it is and how they work. I know that the basic function of the brake is activated to control the brakes of the trailer, connect connected not only with the wiring or in any way on the pedal? *** ATTENTION RV'rs veteran. Do not be afraid. My plan is to these things from a professional and you must disclose to the public before my dumb *** is installed on the open road .****
