We installed a Blue Ox base plate and used the Air Force One brake system but it's for diesel coaches with air brakes. They also make a brake system for gas coaches. The base plate install is somewhat involved requiring removal of the front facia, cutting off the front bumper (base plate replaces it), drilling mounting holes in the chassis cross members and it's a little aggravating to fit the base plate. Unless you're a somewhat decent mechanic, I would recommend paying someone to install it. The easiest way to wire the rear lights is to run the harness underneath the car to the rear, bring the wiring up under the rear bumper cover, up to the taillights, hiding the wiring under the weatherstripping for the rear hatch. Remove the taillights and wire into the various lights using diodes. I can't remember how many, I think 6 or 8.
