I have included a couple of links to the right that will help you. One is a video showing a brake controller installation on a 2009 Silverado. Part of the video does cover the under hood connections.

And I have linked a help article that also explains the location of the wires you will need under the hood. There are 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.
