The Hopkins Agility Brake Controller, part # HM47294, has a power indicator light. If this light is not on when the trailer is connected, I would start by testing the wiring to the brake controller with a circuit tester, part # PTW2993.
The black wire going into the brake controller should have power and the red wire should have power only when the brake pedal is pressed. The blue wire will only have power when the brake controller is activated and if the black wire has power on it. The white wire is the ground for the controller.
If your truck has factory tow package wiring and you do not have power on the black wire then you may need to connect the brake controller power wire under the hood. I am including a link to a FAQ page on installing a brake controller in a Chevrolet truck.
The connections under the hood (see link, step 2) will be made with wires between the fuse box and the firewall underneath a curved bracket. Remove the bracket, the fuse box cover, and the lower cover. There will be a red wire located next to the fuse box that needs to be connected to the nearest power post. You will also need to make sure the fuse is installed in the nearest location to that power post.
I am including a link to the installation instructions on the Hopkins brake controller. It will have a troubleshoot guide to also help you.
