Access the interior and engine compartment modules to inspect all connectors controlling lights, ignition, climate systems, and power outlets. Each terminal is labeled with a code indicating its assigned system. Use a bright flashlight to read markings clearly and photograph the layout before making any adjustments.
Check each circuit individually with a multimeter for voltage and continuity. Begin with high-load circuits such as the blower motor, starter relay, and audio amplifier, then proceed to low-load circuits like dashboard indicators, interior lights, and accessory outlets. Document any irregular readings to pinpoint issues accurately.
Organize replacement links and connectors by amperage rating to prevent overloading low-current circuits or underpowering critical systems. Low-load terminals typically carry 5–10 amperes, while high-load circuits handle 15–30 amperes. Correct placement reduces the risk of shorts and protects sensitive electronic modules.
Maintain a visual reference of all connections by photographing or labeling each terminal. Highlight paths for engine controls, lighting circuits, and auxiliary systems. This ensures correct reassembly and reliable operation during maintenance and component replacement.

Locate the primary distribution module beneath the dashboard on the driver’s side and in the engine compartment near the battery. Each terminal controls specific circuits including headlights, climate controls, power windows, and audio systems. Verify that each connector matches the labeled code before performing any replacements or maintenance.
Check high-load and low-load circuits separately to prevent damage during inspection. High-load lines carry 15–30 amperes and power components such as the radiator fan, starter relay, and heater blower. Low-load terminals carry 5–10 amperes and manage interior lights, instrument panel indicators, and auxiliary outlets. Proper identification ensures safe operation and accurate troubleshooting.
Locating the Interior and Engine Compartment Electrical Modules
Access the cabin module behind the driver’s side kick panel. Remove the protective cover to reveal connectors controlling dashboard lights, window switches, and climate controls. Each terminal is labeled with a code matching the circuit it powers, so photograph the layout before performing any testing or adjustments.
Locate the engine compartment module near the battery on the driver’s side. High-current circuits for the starter relay, radiator fan, and headlight systems are grouped together. Use a multimeter to test each line separately and ensure correct identification of low-load circuits such as sensors, horn, and auxiliary accessories before making replacements or repairs.
