The wires to install a brake controller like the Tekonsha Prodigy P2 # 90885 on your 2012 GMC Yukon Denali will be bundled up under the dash, on the left side of the brake pedal. These can be very difficult to find occasionally so you will probably have to dig in order to find them, but don't give up because they will be there.

I have added a link to a video review of this controller being installed on a Yukon for you to take a look at, as well as a link to our selection of brake controllers for this vehicle.
