Your best options are:
1. Your Owner's Manual: The most reliable source. The owner's manual for your specific 2002 Ford Explorer *should* have a fuse box diagram (often in several locations, covering under-hood and interior fuse panels).
2. Ford's Website: Ford's official website might offer access to owner's manuals or parts diagrams, which sometimes include fuse information. However, finding the exact diagram for your specific year and model can be challenging.
3. Online Repair Manuals (e.g., Chilton, Haynes): These manuals are often available for purchase online and will contain detailed diagrams and information about fuses and relays.
4. Automotive Parts Stores: AutoZone, Advance Auto Parts, and similar stores often have online parts lookups. While they won't directly show a fuse diagram, searching for your Explorer's year and model and selecting "fuses" might lead you to relevant parts information that helps you identify fuse locations and ratings.
Important Note: Be absolutely certain to disconnect the negative (-) battery terminal before working with any fuses or electrical components in your vehicle to prevent injury or damage.
