Pete, check your fuse, as well as your connection, I just went under my truck to confirm, it is the black with green stripe, those reveasre light come from the truck not the aux brake control

Depending on the year of your truck...you should have a main power box under the hood on the driver's side. In there you also need to make sure you put in the relay/fuse for the backup lights to the trailer connector. There are locations for the trailer brakes, trialer lights etc there too, and I think a couple of spots in the fuse panel under the dash.

LOL What they said...(I'm a little slow today)
#4, 20amp fuse/relay...ignition has to be on. And yes...reverse is an option. Even with the trailer package, the most you will get standard is the running lights, turn and brake. the 12v charge for campers and reverse are options. If you got the factory brake controller, then that will be set up, but if you use an aftermarket controller, and hook it to the factory harness to the light plug on the back, you still have to put in the relay/fuses for brake controller, reverse lights and 12v charge.
