* Your Owner's Manual: This is the first and best place to look. The manual should have a dedicated section showing the fuse box layout, with a legend identifying each fuse.
* The Fuse Box Cover: Often, the inside of the fuse box cover itself has a diagram printed on it. This is a smaller diagram but might be sufficient.
* Online Repair Manuals: Sites like Haynes.com or Chilton.com offer repair manuals (often for a fee) that include detailed diagrams and information about the fuse boxes and their components. These are usually more comprehensive than what's in the owner's manual.
* Ford's Website: While less likely to have a readily available diagram, Ford's official website might have some service information available, potentially requiring registration or a dealer visit.
* Ford Dealerships: A Ford dealership service department will certainly have access to diagrams and other service information for your van. This is the most reliable but also the most expensive option.
Important Note: The 1999 Econoline had different fuse box locations depending on the trim level and options. Knowing which fuse box you're looking for (under the hood, in the passenger compartment, etc.) will help you find the correct diagram. Your owner's manual should clarify this.
