Installing a brake controller in your 2012 GMC Sierra is very easy but no plug is present under the dash, but the needed wires are present. You will connect the brake controller wiring with the vehicle wiring already present under the dash. I attached an install video that shows how to do this for you to check out as well. The video shows the P3 # 90195 you referenced installed on a 2011 GMC Sierra.
