* Under the hood: This is the main fuse box and contains larger fuses and relays. It's typically located on the driver's side fender well.
* Inside the cab: This is usually found under the dash, on the driver's side. This box typically houses smaller fuses and is often covered by a panel. The exact location might vary slightly depending on the trim level and options.
To be certain, check your owner's manual. It will have a diagram showing the location and function of each fuse. If you don't have the manual, you can often find a digital copy online by searching for "1991 Ford Ranger owner's manual PDF".
