Locate the interior power distribution panel under the dashboard on the driver side before checking any electrical fault. A second unit is installed in the engine compartment near the battery, handling higher current systems such as cooling fans and ignition circuits.
Each protected slot corresponds to a specific function, including lighting, HVAC controls, radio, and auxiliary power outlets. Misreading the layout often leads to replacing the wrong component, so always match the slot number with a vehicle-specific chart. Panel layouts vary slightly depending on equipment configuration.
Inspect the metal strip inside each protective insert to confirm failure. A broken link or burn mark indicates a blown element. Use the exact amperage value printed on top when installing a replacement to prevent wiring damage or malfunction of connected modules.
Keep a puller tool nearby for safe removal, especially in tight spaces under the dashboard. Regular checks of these components help maintain stable operation of electrical systems and reduce time spent diagnosing faults.

Match each numbered slot to its circuit using the chart printed on the panel cover before removing any component. The interior distribution unit manages cabin systems, while the engine compartment unit handles high-load circuits such as ignition, cooling, and charging systems.
The cabin panel includes grouped assignments for convenience:
- Audio system and dashboard electronics
- Power windows and door locks
- Interior lighting and instrument cluster
- Climate control module
Each slot has a fixed amperage rating, typically ranging from 5A to 30A. Lower values protect sensitive electronics, while higher values support motors and power outlets. Always confirm both slot number and rating before replacement.
Engine Compartment Power Distribution Layout
High-current circuits are separated to reduce overload risk. This section usually includes:
- Fuel pump relay and control circuit
- Cooling fan motors
- Headlamp power supply
- Engine control module feed
Relays in this area are labeled and often interchangeable only within identical part numbers. Incorrect placement may interrupt starting or charging functions, so verify markings before swapping components.
Where the fuse panels are located in a 2006 Ford E350 Super Duty and how to access them
Check the driver-side lower dashboard area first, where the interior power distribution panel is mounted behind a removable plastic cover. Pull the cover outward using the molded tab, then expose the numbered slots arranged in rows.
The second panel sits under the hood on the left side near the battery tray. It is enclosed in a sealed plastic housing designed to protect high-current circuits from moisture and debris. Release the side clips and lift the lid straight up to avoid damaging the locking tabs.
Use a flashlight to read labels clearly, since markings can be small and partially hidden by wiring. Align your viewing angle with the panel orientation to prevent selecting the wrong slot during inspection or replacement.
Interior Panel Access Tips
Slide the driver seat back fully to create working space. Kneel outside the vehicle and reach inward rather than forcing your body under the dashboard. Grip each component firmly and pull straight out to avoid bending contacts.
Engine Compartment Panel Access Tips
Turn off the ignition and remove the key before opening the under-hood unit. Keep metal tools away from battery terminals to prevent short circuits. After completing work, press the cover evenly until all clips snap into place, ensuring proper sealing against dirt and water.
Store a small puller tool inside the cabin for quick access during roadside checks. Regular inspection of both panels helps detect worn or overheated components before they cause larger electrical failures.
