Locate the main power hub under the dashboard near the driver’s side kick panel. Accessing this unit requires removing the small trim panel and loosening two retaining screws. Use a flashlight to identify each terminal and maintain a record of connections.
The engine compartment contains a secondary power module above the battery. Disconnect the negative terminal before inspecting any connections to prevent shorts. Label wires or take photos for reference before any adjustments.
Each relay within the modules is keyed to a specific circuit, including lighting, ignition, and climate controls. Check the stamped numbers on each relay for alignment with the electrical chart found inside the module cover.
When inspecting circuits, avoid metal tools that could bridge terminals. Plastic-tipped probes or insulated screwdrivers reduce the risk of accidental shorts.
For repeated maintenance, maintain a reference chart of all terminal positions and relay locations. This reduces errors and speeds up troubleshooting for headlights, HVAC, and auxiliary components.
Electrical Panel Reference and Maintenance Guide

Access the primary control module beneath the driver-side dashboard by removing the lower trim panel. Check for loose terminals or corrosion on the connectors and clean contacts with electrical-grade contact cleaner before reassembly. Mark each connection to maintain proper circuit alignment.
Engine compartment power distribution is located near the battery housing. Inspect relays and connectors for signs of heat damage or moisture intrusion. Replace any terminals showing discoloration to prevent intermittent failures in ignition or lighting circuits.
Maintain a reference chart of all relay positions and circuit assignments. Labeling each slot ensures faster troubleshooting for headlights, climate systems, and auxiliary components, reducing misconnection risks.
Perform periodic inspections every 12 months or after high-humidity exposure. Check mounting screws, clips, and wire harnesses for tightness and integrity to prevent rattling, shorts, or signal loss across critical circuits.
Locating Main Interior and Engine Power Hubs

Access the central interior power hub by opening the driver-side lower panel. Inspect connections for signs of wear or corrosion and tighten any loose terminals. Ensure that the wiring harness is properly routed to avoid interference with pedals or steering components.
The primary engine compartment power module is mounted near the battery and air intake assembly. Check that all relay units and high-current terminals are secure and free from moisture or debris. Periodic visual inspections help maintain reliable operation of ignition circuits, lighting, and auxiliary devices.
