Unfortunately, the exact fuse number isn't consistently documented across all sources. Your best bet is to:
1. Locate the underhood fuse box: This is usually a black plastic box near the battery.
2. Consult the owner's manual: Your owner's manual should have a fuse box diagram showing the location of the cigarette lighter fuse. This is the most reliable source.
3. Check the fuse box cover: The cover itself often has a diagram showing the fuses and their corresponding circuits.
4. Look for a fuse labeled "Power Outlet," "Accessory," or similar: If the diagram isn't clear, look for a fuse that seems likely to control the power outlet.
If you can't find it using these methods, a local auto parts store or mechanic should be able to help you identify the correct fuse. They often have diagrams for various Ford models.
