Expert Reply:
Under the hood of your truck there are a few connections that need to be made near the fuse box in order to complete the 7-way's wiring. This will allow the brake output and 12 volt accessory circuit to be complete.
Check out the help article I attached to see how to do this. You will have to scroll about half way down the page to see how this is done.
