Locate the primary control unit under the dashboard on the passenger side and remove the cover carefully to expose all numbered terminals. Record the position of each slot before handling any modules to prevent misplacement and maintain correct circuit connections.
High-current terminals power headlights, interior lighting, and auxiliary outlets. Check continuity using a multimeter before reinserting modules, particularly those connected to sensors or entertainment components, to avoid short circuits.
The secondary panel under the hood handles circuits for the engine, cooling fans, and power distribution. Inspect all connectors for looseness or corrosion, and clean terminals gently if oxidation is present to maintain reliable operation.
When adding aftermarket electronics, label each connection during installation to prevent cross-wiring. Keeping a detailed log of replaced or inspected modules supports consistent performance and simplifies troubleshooting future issues.
Electrical Panel Layout Guide for Compact Sedan

Access the main control hub located beneath the dashboard on the passenger side and remove the protective cover carefully to reveal all numbered terminals. Document each slot before handling any modules to maintain proper connections across interior lighting and accessory circuits.
High-current terminals supply power to headlights, cabin lights, and auxiliary outlets. Test continuity using a multimeter before reinserting any components, paying special attention to circuits linked to sensors, ignition, and entertainment systems.
The secondary panel in the engine compartment manages circuits for the starter, alternator, cooling fans, and power distribution to the drivetrain. Inspect connectors for looseness, corrosion, or damage, and clean terminals gently if oxidation is present to prevent intermittent faults.
When installing aftermarket electronics, label all connections to avoid miswiring between signal and power lines. Maintaining a record of replaced or inspected modules ensures reliable operation and simplifies troubleshooting of recurring electrical issues.
Locate the Main Panel and Identify Slot Functions

Access the primary electrical hub beneath the passenger-side dashboard and remove the cover carefully to reveal all numbered terminals. Document each slot before removing or testing modules to ensure correct placement and avoid disrupting interior circuits.
The main panel contains high-current and low-amp slots assigned to specific systems:
- Headlights and tail lights
- Cabin lighting and interior accessories
- Heated seats and power outlets
- Sensor and ignition circuits
- Infotainment and audio modules
Check continuity with a multimeter before reinserting any modules, and label each connector during inspection to prevent miswiring. Keeping a reference of slot assignments speeds up troubleshooting and reduces the risk of electrical faults.
