In order to install a 7-way trailer connector on your 2002 Ford F-450, I recommend using the 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring part # HM40975-11998. Unfortunately, we do not have any plug and play trailer connectors compatible with your vehicle therefore hardwiring will be your only option.

There should be a pigtail or group of blunt cut wires that are tied off on the drivers side frame near the spare tire that will hold the functions for the above 7-way. You will need to use a circuit tester like part # PTW2993 to determine the function of each wire as the wire color to function ratio across vehicles is not always a constant.

Then for a brake controller, I recommend using the Tekonsha Voyager Trailer Brake Controller part # 39510 which is easy to use, cost effective, and well reviewed. You can use the plug-in adapter part # 3035-P to install it on the vehicle. If you need help installing the above wiring harness I have attached a sample install video which you can use to help guide you.

No, the brake output (blue) and 12 volt power (black) wires should already be ran to the rear of the vehicle on the same connector or group of wires that hold the signals for the turn, brake, and running light circuits. As previously mentioned, the connector/bundle should be tied off on the drivers side frame near the spare tire.
