Hey Devin, the Prodigy P2 brake controller part # 90885 is a great controller and it comes with everything needed to install in your 2009 GMC Sierra 1500. Basically your truck has brake controller wires already present under the dash that you would need to run this controllers wiring straight to. Once you do that and make a couple connections under the hood of your truck the controller will be active and ready to use. I attached a help article on this for you to check out as well.
