On your 2014 GMC Sierra 1500 there is a junction box with a black cover on it located on the driver's side floorboard, way in the back, to the left of the brake pedal. There should be an empty spot to plug in the wiring harness located in the upper left corner. I have included a link to a video that should help. It is a different harness but it plugs into the same spot.
