Unfortunately you are almost on your own when it comes to electrical problems on those (2003 - 2009) medium duty trucks. What is shown for wiring diagrams in the repair manual is often not how the truck is actually wired.

To make it even more of a challenge the placard on the fuse panel cover also does not match how the truck is wired.
Besides being powered through the fuses some of those trucks are wired so that the switch controls a relay rather than directly powering the lights.
