When choosing between a time delay and proportional brake controller I will always go with proportional. The reason is that a proportional brake controller will actuate the trailer brakes in proportion to how much the vehicle is braking. This is the safest braking situation. It will also reduce wear and tear on the vehicle and trailer brakes. I have included a link to our brake controller FAQ article for you to view.
For your 2005 GMC Sierra, I recommend the Tekonsha P2 # 90885 and wiring harness # 3015-P. The P2 is one of our most popular controllers because it is easy to set up and easy to use. The # 3015-P is a vehicle specific wiring harness that plugs directly into a port on the truck.
The port is located in an electrical junction box behind and to the left of the brake pedal. Just remove the cover, plug the wiring harness in to the empty port on the top row, second from the left, replace the cover and connect the other end to the brake controller. I have included a link to a video showing this installation on the same model and year truck.
If your truck did not come with a factory 7-Way trailer connector at the back, you will need to add one using Twist-in, 7-Pole, RV-Style Trailer Connector, # PK11916. I have included a video showing a typical installation of this connector as well as a link to the brake controller instructions.
