* Owner's Manual: The most reliable source. Check the owner's manual that came with the truck. It should have a detailed diagram showing the location of both fuse boxes (under the hood and inside the cabin, if applicable) and what each fuse controls.
* Repair Manual: A Haynes or Chilton repair manual specific to a 1997 Ford Ranger will have detailed diagrams and explanations of the fuse boxes. These are usually available at auto parts stores or online.
* Online Forums: Websites and forums dedicated to Ford Rangers (like Ford-trucks.com or similar) often have members who have shared photos or scans of their fuse box diagrams. Searching for "1997 Ford Ranger fuse box diagram" on these sites might yield results.
* Online Parts Retailers: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts may offer access to diagrams if you search for your specific vehicle year and model. Their online catalogs sometimes include schematics.
Important Note: There are often *two* fuse boxes in a 1997 Ford Ranger: one under the hood and one inside the cab (usually under the dash). Make sure you're looking for a diagram of the correct box. The owner's manual will clearly indicate their locations.
Remember to always disconnect the negative battery terminal before working with fuses or electrical components to prevent accidental shorts or damage.
