The factory-installed integrated brake controller in your 2013 Chevrolet Silverado uses an OEM connector that is not compatible with aftermarket brake controllers from Tekonsha and others. But since there is wiring in place under the dash to allow for aftermarket brake controller installation you can still install a versatile and easy-to-use proportional controller like the Tekonsha Prodigy P2 # 90885. This is among the most popular and reliable units offered and it is shown in the linked video.
The linked article specifically outlines the process for splicing such a brake controller into the existing wiring under your dash. The wires are located above your left shin as you are seated in the driver's seat.
The P2 comes with a pigtail wiring harness to allow you to splice into the under-dash vehicle wiring. You will also need enough 12-gauge blue wire, part # 10-1-1, to reach from the brake controller to your 7-way vehicle connector. In the engine compartment you will need to make two additional wiring connections to activate the wiring for the controller's 12V power and for the trailer's charging circuit. All of this is explained in the linked article.
