This is the original wiring diagram printed by Ford for dealer mechanics. You can follow the wiring in your truck from bumper-to-bumper. It will help you to understand connector configurations, and locate & identify circuits, relays, and grounds. Although the schematic is in black and white, the color of each wire is noted. You will not find this diagram in your shop manual. The schematic measures 11" x 17" when folded up, and opens up to 11" by 29". Diagrams may be folded in half for shipping. The diagram pictured is an example of this type when unfolded, but is not the actual diagram for your vehicle. Buy now for the best electrical repair info--the factory wiring diagram.
