As far as wiring, in order to add a brake controller, you first need to have a 4-way wiring harness installed on your vehicle. If you need that harness, I recommend the Curt Wiring Harness with 4-Pole Flat Trailer Connector # C56259. The T-One includes a ModuLite power converter to ensure that your vehicle's wiring matches that of your trailer.
After the 4-way is installed, you are ready for the 7-way (which will give you the ability to install a brake controller). You will need the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7 in addition to the Curt.
To add a brake controller, I recommend the Tekonsha Voyager # 39510 or the Curt Echo # C51180. Both of these controllers are proportional controllers which means that the controller activates the trailer brakes in proportion to your vehicle's braking action. The Voyager is more of a traditional-style controller than requires mounting into the dashboard of your vehicle near the steering wheel. On the other hand, the Curt Echo allows you to control the settings of your controller with the ease of your Smart device.
If you need help installing any of these accessories, I went ahead and linked walk-through videos to guide you through the process.
