Check the driver side dashboard and engine compartment units first to locate the correct circuit for any electrical issue. The interior unit is positioned behind a small cover near the lower dash, while the engine bay unit sits close to the battery and main wiring lines.
Use the labeling on the cover to match each slot with its function such as headlights, wipers, audio system, or cooling fan. Typical ratings range from 10A for low-load electronics to 30A or more for motors and high-current systems.
Remove each protective insert carefully and inspect the metal strip inside. A visible break or burn mark indicates failure. Replace with the same amperage value to prevent wiring damage or repeated issues.
When multiple components stop working at once, check shared circuits and relays. Common fault points include worn wiring near hinges, loose connectors, and corrosion around battery terminals.

Match each slot to its assigned system using the cover legend before removing any protective element. The interior electrical unit groups lighting, audio, and dashboard functions in adjacent rows, while higher load circuits such as blower motor and rear defroster are placed in separate positions with higher amperage ratings.
Trace each circuit from the power source through relays to the component for accurate diagnostics. For example, if headlights fail, check the corresponding slot, then verify the relay position and wiring path leading to the front harness. Consistent grouping allows quick identification: cabin electronics in the lower dash unit, engine-related systems in the compartment near the battery.
Exact locations of interior and engine bay fuse boxes in 1998 Outback
Open the driver door and inspect the lower dashboard area to find the interior electrical unit. It is mounted to the left of the steering column, slightly above the footwell trim and hidden behind a small removable cover.
Pull the plastic cover outward to expose the internal layout. The cover usually has a printed chart showing slot positions and assigned circuits.
- Position: left side of steering column
- Height: above driver footwell
- Access: snap-off plastic cover
This cabin unit controls systems such as interior lighting, radio, power locks, and instrument cluster. Grouped placement allows quick access during troubleshooting.
Lift the hood and locate the main power distribution unit near the battery for engine-related circuits. It sits close to the fender, connected to thicker wiring harnesses.
- Release the hood latch inside the cabin
- Secure the hood with the support rod
- Find the black rectangular housing near the battery
- Unclip the side latches and remove the cover
This engine compartment unit handles higher current systems such as cooling fans, ignition components, and charging circuits. Larger inserts and relays are positioned here due to increased load demands.
Reinstall both covers tightly after inspection to protect internal contacts from dirt, moisture, and heat exposure.
