Check the passenger compartment panel first for quick access to circuits controlling interior lighting, infotainment, and climate systems. This compartment is located under the dashboard on the driver’s side and features a removable cover for clear labeling of each protective element.
Inspect the engine compartment relay center to identify circuits for headlights, cooling fans, and ignition modules. This relay hub is mounted near the battery and uses color-coded holders to distinguish amperage ratings for each component, helping prevent mismatched replacements.
Use a printed or digital layout reference when replacing or testing any protective device. Matching each slot with its corresponding system ensures that critical electronics like airbags, power seats, and window motors remain functional while avoiding accidental short circuits.
Electrical Panel Layout Guide
Start with the interior control panel located beneath the driver’s side dashboard for immediate access to circuits managing cabin lighting, audio system, and climate control. Each holder is labeled with a numeric code corresponding to its specific system, allowing accurate identification without trial and error.
Examine the engine compartment relay center to locate circuits that supply power to headlights, cooling fans, and the ignition system. The center uses differently colored slots to indicate amperage levels, reducing the risk of installing a mismatched protective element.
Keep a reference chart handy while testing or swapping any protective component. This ensures that critical functions such as power windows, seat motors, and airbag modules remain operational, and prevents accidental electrical shorts or blown circuits during maintenance.

Access the cabin control panel under the driver’s side dashboard for circuits controlling interior lighting, infotainment, and climate systems. The cover can be removed by pressing the release tabs, revealing clearly labeled slots for each protective element.
Check the engine compartment relay center near the battery to identify circuits for headlights, cooling fans, and ignition modules. The center uses color-coded holders indicating amperage, which prevents mismatched replacements and simplifies troubleshooting.
Additional protective hubs are located behind the glove compartment and near the trunk area. These panels manage power distribution for rear electronics, audio amplifiers, and accessory outlets.
- Driver’s side under-dash panel – interior circuits
- Engine compartment relay center – high-power systems
- Glove compartment panel – auxiliary electronics
- Rear trunk panel – cargo and rear accessory circuits
Maintain a reference chart while testing or replacing any protective component to ensure that critical functions such as airbags, power seats, and window motors remain operational without causing shorts or blown elements.
