You didn't mention what year GMC Sierra you have but the issue you mentioned is pretty typical on GM trucks as there's a couple connections that need to be made under the hood for the trailer wiring 12 volt accessory circuit to be complete.
I attached two help articles below that cover the two GM truck generations requirements to install a brake controller. In that there will be how to activate the circuit.
