Check the interior electrical panel under the dashboard first, as it contains most low-amperage circuits for lighting, radio, and accessories, making it the primary point for quick diagnostics.
The driver-side lower dash houses a compact block with blade-type links arranged in rows. Each slot is marked by amperage values such as 7.5A, 10A, or 15A. Match these ratings with the printed legend on the cover or service manual to identify which circuit controls each component. This helps avoid removing unnecessary parts while tracing faults.
Under the hood, a second distribution unit sits near the battery and includes larger links for systems like cooling fans, ignition supply, and charging circuits. These components handle higher current loads and should be inspected with care, using proper tools to avoid damaging terminals.
Use a multimeter to verify continuity instead of relying only on visual checks, since hairline breaks inside a link may not be visible. Always replace with the same amperage rating to maintain circuit protection and prevent wiring damage.

Use the interior panel layout chart to match each slot number with its assigned circuit, focusing first on common failure points such as radio, brake lights, and dashboard illumination. The under-dash block contains small blade links arranged in a grid, each labeled with amperage values like 7.5A or 10A; these correspond to specific electrical paths listed on the cover legend.
For accurate circuit identification, trace abbreviations such as ACC, IG, or STOP printed near each position and compare them with a service manual reference to confirm function. The engine compartment distribution unit includes higher-capacity links for systems like radiator fans and ignition supply, and these are typically housed in a sealed case near the battery. Check continuity with a multimeter instead of relying on visual inspection, and replace only with identical amperage ratings to avoid overheating wires or disabling connected components.

Access the interior electrical panel beneath the driver side dashboard and use the printed slot numbers to identify each protected circuit before removing any component.
The panel is arranged in horizontal rows with small blade links rated between 7.5A and 20A. Each position connects to a specific function such as turn signals, brake lights, heater controls, or audio system. The cover includes a molded reference map that aligns with slot numbering, allowing quick matching without disassembling surrounding trim.
Pay attention to labeled abbreviations like ACC for accessory circuits, IG for ignition-fed lines, and STOP for brake light supply. These markings provide direct clues about which system is affected when a link fails, reducing guesswork during troubleshooting.
Use a multimeter to confirm continuity across each link while it remains seated in place, and replace damaged units only with identical amperage ratings to maintain correct circuit protection and avoid wiring damage.
