Here are the best places to look:
* Your Owner's Manual: The most likely place to start. The owner's manual should have a fuse box diagram, often located in the section dealing with fuses and lights.
* Ford's Website: Ford's website might have some information, but finding a specific wiring diagram for that model year might be difficult. You may need to navigate through their parts and service sections or even contact their customer support.
* Haynes or Chilton Repair Manuals: These aftermarket repair manuals are known for having detailed diagrams and information. You'll need to specify the exact model of your van (E-150, E-250, E-350, etc., and whether it's a cargo van, passenger van, etc.) when purchasing one. These are usually available at auto parts stores or online retailers.
* Online Forums: Websites and forums dedicated to Ford vans (like Ford-trucks.com or similar) may have members who have already shared or found diagrams. Searching the forums for your specific van model and year is worth a try.
* Local Auto Parts Store: Auto parts stores (like AutoZone, Advance Auto Parts, etc.) often have access to repair information databases. They might be able to print you a diagram, or at least point you to the right resource.
Important Note: When working with electrical systems, always disconnect the negative battery terminal before starting any work to prevent accidental short circuits or shocks. If you're not comfortable working with automotive electrical systems, it's best to seek the help of a qualified mechanic.
