To find the brake switch on a vehicle what you need to do normally is test the wires running to the brake pedal switch till you find a circuit that has voltage only when the brakes are applied.

That being said an easy way to find it for your specific vehicle (2015 Chevy Silverado 2500) would be to plug the brake controller harness part # 3016 into the junction box under the dash of your truck and then tap into the red wire of the connector.

I attached an install video that shows how this harness would install as well.
