Expert Reply:

Installation of a brake controller on the 2006 Chevrolet Silverado requires using the Universal Brake Control Wiring Adapter, item # 3015-S, making some connections under the hood and running a wire to the rear of the vehicle to the trailer connector.

We have a informational article that details how to install a brake controller on your vehicle, see link. Start at the section labeled Vehicles without Factory Installed 7-way and go to step two to begin. In photo D you will see a blue wire with a connector on the end that will need to be cut off. Splice an appropriate length of 10 gauge wire, item # 10-1-1, to this wire and run it to the rear of the vehicle and attach it to the proper circuit in your trailer connector.

If you do not have power to the brake controller in the cab of your pickup, after connecting the adapter to the brake controller and fuse block, you will find a red wire next to the blue wire under the hood. This wire will need to be attached to the power post closest to the cab and a 30 amp fuse will be needed in the location nearest this power post. An M8 Hex Flange Nut, item # 185917, is needed to secure the wire to this stud.
