You certainly can!
Installing a brake controller is fairly easy if you are familiar with running wiring. To install a brake controller like the popular Tekonsha Prodigy P3 # 90195 you will need to run the wires on the pigtail to the following functions:
Black - 12V Power
White - Ground
Blue - Brake Controller Pin on 7-Way
Red - COLD Side of the Stop Light Switch (only gets hot when you brake pedal is pressed)
You can use a circuit tester like part # PTW2993 to find the cold side of your stop light switch. You will need to install a 20A circuit breaker, like part # 9506P, on the 12V power wire 6" away from the negative battery terminal.
