Expert Reply:

On your 2007 Chevrolet Suburban 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.

The battery charge wire and the power wire to the brake control have different size eyelets on them and will connect to the threaded studs under the Gray handle at the front of the fuse box. The two threaded studs are different size so you will need to purchase a M6 nut like # 185916, and a M8 nut like # 185917, to use to attach the wires to the studs.

If the wires are already attached correctly you will want to check the fuses in the fuse box that are designated for the battery charge wire and the brake control wire. It should be listed on the lid of the fuse box or in your owners manual. I am including a link to an install video that will show these wires being connected on a 2011 Chevrolet Suburban. The year of the vehicle is different but the installation would be the same as your 2007 Suburban.
