It would be very rare if your 2015 GMC Sierra 1500 didn't have a round connector underneath the rear bumper area for the 7-way part # 74682 to fit. I would check there as all versions of your truck are supposed to come with that.
If not, you'd need to start with a universal install 4-way like the part # 119250KIT which you can then convert to a 7-way with the part # 37185.
