Question:
Is the 2018 brake controller a pig tail plug or 4 wires that you have to splice together?

To install a brake controller in your 2018 GMC Sierra 1500 there is a simple plug-in adapter that will connect to the back of the controller and then plug into the port under your dash. For that you'd only need the part # 3016 to install a Tekonsha brake controller like the P3 part # 90195.
