Camper you just bought has electric brakes. Brake controller controls those e-brakes connecting them electrically to your brake pedal. Signal goes through your connector.
"Tow package" doesn't necessarily mean you have a tranny cooler. Lots of times if it's dealer installed you may only have a hitch and wiring. Something to check out. BTW, I've towed many thousands of miles without a transmission cooler. If you take it easy it's not an absolute must IMHO, depending on the vehicle.
