Access the driver-side lower dash compartment first, then check the under-hood unit near the battery to identify faulty links. Match each slot with its printed label and amperage rating before removal to prevent damage.
Cabin distribution panel controls interior lights, instrument cluster, audio system, and power outlets. Typical ratings range from 7.5A for indicator lights to 20A for window and door lock motors. Use a continuity tester to verify connections instead of relying on visual inspection.
Engine compartment protection unit handles high-current circuits such as ignition, alternator, cooling fans, and ABS module, often rated between 30A and 80A. Disconnect the negative battery terminal before servicing this area to avoid short circuits or module failure.
Keep spare links in the same compartment, organized by amperage. Replace any damaged element with one matching the exact rating to maintain safe operation and prevent wiring overheating.

Start by opening the driver-side lower dash panel to access the interior electrical unit, then inspect the engine compartment module near the battery for high-current circuits. Verify each slot number against the printed label before removing any link.
The cabin panel handles low to mid-current systems, including:
- Interior lighting and dashboard instruments
- Power outlets and audio system
- Door locks and window motors
- Control modules and relays
The engine bay module supports major components such as cooling fans, ignition system, ABS module, and alternator. Ratings typically range from 30A to 80A. Disconnect the negative battery terminal before servicing to prevent short circuits or damage.
Spare links are usually stored in the same compartment in common amperages like 10A, 15A, and 20A. Replace any damaged element with one matching the exact rating to ensure proper operation and prevent wiring or component failure.

Remove the lower dash cover on the driver side to access the cabin electrical panel. Check the printed chart on the inside of the cover to identify each slot by number and its corresponding current rating before attempting any replacement.
Lighting and instrument circuits typically occupy the first row of slots. Ratings are usually 7.5A for dome lights, side markers, and instrument cluster indicators. Test each element with a continuity meter to confirm functionality.
Accessory and control circuits such as audio, power outlets, and door locks usually range from 10A to 20A. Locate these slots in the center section of the panel for quick access during troubleshooting or replacement.
Common slot assignments
- Slots 1–4: interior lighting and indicators
- Slots 5–8: audio system and power outlets
- Slots 9–12: power windows, door locks, and control relays
Spare links and maintenance tips
Spare elements are clipped inside the panel in 10A, 15A, and 20A ratings. Always replace a damaged unit with the exact rating to avoid overheating wires or damaging connected components.
