Locate the cabin-mounted power panel beneath the dashboard on the driver side to access circuits for lighting, audio system, and accessory outlets. Each slot is numbered and paired with a specific amperage rating, commonly 5A to 20A, allowing quick identification of low and mid-load electrical lines.
Open the engine compartment distribution unit next to the battery to find high-current protection elements for systems such as cooling fans, starter motor, and braking electronics. Larger cartridge-style inserts and relays are arranged in a structured layout, with clear grouping by function.
Use the cover legend or service manual chart to match each position with its assigned circuit, then confirm wiring paths by color codes. Red wires typically indicate constant battery feed, while other colors correspond to ignition-switched or accessory-controlled circuits.
Inspect each contact point and ensure firm seating, as loose or oxidized terminals can interrupt current flow and lead to intermittent faults across multiple systems.

Use the panel cover chart to align each numbered slot with its assigned circuit, beginning with the cabin unit under the dashboard where most interior systems are grouped. Lighting, radio, and accessory outlets are placed in lower and mid-range positions for quick access.
Slots handling low-current circuits typically use 5A to 10A inserts, supporting dashboard illumination, control switches, and onboard electronics. These are arranged along the outer rows of the panel for easier identification during inspection.
Mid-range positions distribute power to higher-load components such as power windows, wipers, and central locking. These slots usually carry 15A or 20A ratings and are located toward the center of the grid layout.
Check the engine compartment power distribution center for high-load circuits, where larger cartridge-style elements supply systems like cooling fans, ABS module, and ignition control. These are arranged in a separate enclosure near the battery.
Relays are positioned adjacent to high-current inserts and control switching for key systems including starter motor, fuel pump, and air conditioning clutch. Their placement follows a grouped layout based on function.
Trace wiring by color coding from each slot to its destination, using red for constant battery feed and other colors for switched or accessory-controlled lines. This helps verify circuit paths without removing multiple components.
Inspect terminal contact points and ensure firm seating, as loose or oxidized connections can interrupt current flow and cause inconsistent operation across electrical systems.
Dashboard Fuse Panel Slot Numbers and Circuit Assignments
Read the numbered grid on the dashboard-mounted panel and match each slot to its circuit using the cover legend, focusing on low and mid-load systems routed through this area. The layout follows a row-based structure, where outer positions typically handle smaller electrical loads and central slots support higher demand components.
Use this reference for common assignments:
- Slots 1–4: instrument cluster, interior lighting, and control switches (5A–10A)
- Slots 5–8: radio system, accessory outlets, and memory circuits (10A–15A)
- Slots 9–12: power windows, door locks, and wiper system (15A–20A)
- Slots 13–16: auxiliary features and optional equipment depending on trim level
Verify amperage markings and trace wire colors from the rear connectors to confirm circuit routing and avoid incorrect replacement.
