* Owner's Manual: The most reliable source. Check the glove compartment or the area where you store your vehicle documents. The fuse box diagrams are usually located within the manual itself.
* Fuse Box Cover: Often, the inside of the fuse box cover itself has a small diagram showing the fuse layout and what each fuse protects. There may be multiple fuse boxes (under the hood and in the cab).
* Ford's Website: Ford's website might have owner's manuals available for download, even for older models like your 2002 F350. Searching their site for "2002 F350 owner's manual" should yield results.
* Online Forums: Searching online forums dedicated to Ford trucks (like Ford-trucks.com or similar) might reveal someone who has posted a picture or scan of the fuse chart. However, always double-check the information found on forums as it's user-generated content.
* Repair Manuals: A comprehensive repair manual for your specific year and model (like a Haynes or Chilton manual) will certainly include detailed fuse diagrams and explanations.
Remember that there may be multiple fuse boxes in your truck – one under the hood and potentially one inside the cab. The owner's manual will clearly identify the location and contents of each.
