When wiring the Hopkins Agility Brake Controller, # HM47295, to your 2008 Chevrolet Silverado, there will be two steps that you will have to take to ensure the brake controller will operate properly.

The first step is to connect the wires from the brake controller to the vehicles brake control wiring harness that you have already located.

The black wire from the brake controller will connect to the red wire with a black stripe. This will supply the 12 volt power to the brake controller. The white wire from the brake controller is the ground and that will attach to the white wire. The blue wire from the brake controller will attach to the blue wire for the brake output circuit and the red wire from the brake controller will connect to the light blue wire with the white stripe for the brake light signal.

The second step is to locate two wires under the hood that have to be connected to make the tow package functional.

One is the power wire to the brake control and the other is the battery charge line to the 7 way connector. These wires are both Red/Black with eyelets on them. They are coiled up under the hood and will need to be connected to the under hood fuse box. One of the wires is located between the under hood fuse box and the left (driver) side fender. The other is located under the master cylinder/brake booster assembly.

I have attached a photo showing the locations of these wires. I have also attached an article on installing a brake controller on your vehicle that explains what I have mentioned.
