Fuse Box Location and Diagrams Guide: Ford F-150 (1997-1998)
This extensive reference shows Ford F-150 (1997–1998) fuse box locations and diagrams. Fuse panels can be accessed and identified to fix electrical faults and maintain your truck.
REPLACING BLOWN FUSES
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken element. Check the appropriate fuses before replacing any electrical components.
Even after a fuse is replaced, it may continue to blow if the cause of the overload is not identified and corrected. If a fuse continues to blow, have the vehicle’s electrical system checked. Standard fuse amperage ratings and colors
| Fuse rating | Color |
| 7.5 amp | Brown |
| 10 amp | Red |
| 15 amp | Blue |
| 20 amp | Yellow |
| 30 amp | Light green |
| 30 amp fuse link | Pink |

| 60 amp fuse link | Yellow |
| 80 amp fuse link | Black |
| 100 amp fuse link | Blue |
Instrument panel fuses
Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
