The utility vehicle from the early 2020s equipped for emergency duty uses a dual power distribution setup, and the primary panel sits beneath the dashboard on the driver’s side. Access requires removing the lower trim panel and identifying the numbered slots printed on the inner cover. Each cavity corresponds to a specific circuit: lighting modules, radio system, siren controller, onboard computer, and auxiliary power outlets. Always match the amperage rating stamped on the metal strip with the value listed on the cover chart to avoid damage to sensitive electronics.
A secondary distribution unit is installed in the engine compartment, near the battery. This section handles higher-load systems such as cooling fans, ABS, and ignition control. The lid includes a molded layout showing relay positions and cartridge-style protectors. Pay attention to the difference between micro, mini, and cartridge types; installing the wrong size leads to poor contact or overheating. For troubleshooting, use a multimeter to confirm continuity rather than relying solely on visual inspection.
Special-service configurations often include additional circuits not present in civilian versions. These may power communication arrays, surveillance equipment, and emergency lighting bars. The slot allocation for these extras is usually labeled with abbreviations like “AUX1,” “COMMS,” or “SIREN.” Document the original placement before removing any component, since retrofitted wiring can vary between units even within the same production batch.
For quick identification, the numbering sequence typically runs left to right, top to bottom, though some panels reverse the order. Cross-reference the numbering with the printed key on the cover rather than guessing. Incorrect placement may disable critical driving systems, including transmission control or brake assistance. Keeping a printed reference sheet inside the glove compartment speeds up field repairs and reduces downtime during operation.

Locate the primary power distribution unit under the hood near the driver-side fender and verify circuit labels directly on the cover before touching any element; mismatched amperage inserts cause recurring faults in lighting and radio systems. Use a puller tool instead of pliers to avoid damaging contacts, and cross-check each slot against the printed legend to identify circuits for siren, auxiliary lighting, and onboard computer modules.
Cabin Compartment Panel Access
Inside the cabin, the secondary relay and circuit panel sits beneath the dashboard on the driver side; remove the trim carefully to avoid breaking clips. This section handles climate control, infotainment, and door systems. If a function stops working, test the slot with a multimeter rather than visual inspection–microfractures in the metal strip are common and invisible. Replace only with identical rating units (e.g., 10A, 15A, 20A), as oversizing leads to wiring overheating.
Troubleshooting and Replacement Tips
For repeated failures, inspect grounding points near the chassis and battery terminals, since poor grounding often mimics circuit overload. Keep a printed layout chart in the glove compartment for quick reference during roadside checks. After installing a new element, turn the ignition to accessory mode first to confirm stability before full startup; sudden load spikes during engine ignition can immediately damage a newly installed component if an underlying short remains unresolved.

Check the passenger compartment panel first: it sits behind the glove compartment on the right side of the dashboard. Lower the glove compartment by pressing the side stops inward, then let it drop fully; the access cover becomes visible immediately behind it. Remove the cover by pulling the side tabs–no tools required. This panel contains circuits tied to cabin electronics such as infotainment, climate control, and auxiliary equipment wiring often added for duty use.
Under the hood, locate the power distribution unit on the driver’s side near the battery and strut tower. It is enclosed in a rectangular black housing with a snap-on lid; release the two front clips and lift upward. Inside are high-amperage links for systems like cooling fans, ABS, and charging components. For quick identification, the lid’s underside includes a printed layout; align it with the slot positions before removing any link to avoid mismatches. Always disconnect the negative battery terminal before servicing high-current circuits to prevent arcing.
