Access the primary panel under the driver’s side dashboard for cabin circuits. Turn off the ignition and remove the keys before opening the cover to avoid accidental shorts.
Identify each slot by the printed numbers and color-coded ratings. High-load circuits include headlights, fuel pump, and cooling fans, while smaller slots control interior lighting, infotainment, and climate modules.
Use a multimeter to test continuity before replacing any component. Swap a blown unit with one of identical amperage to maintain circuit integrity and prevent damage to wiring harnesses.
Keep a reference chart of the panel layout. Recording which circuits control which systems reduces confusion during maintenance and ensures proper placement of replacement elements.
Electrical Panel Guide for GT Model
Locate the primary electrical enclosure under the driver’s side dashboard. Release the lower trim panel carefully to expose the rectangular case with a snap-on lid securing all circuits.
Check the secondary compartment near the battery in the engine bay. This area houses high-amperage connections for starter circuits, alternator, and cooling fans. Ensure terminals are clean and tightly connected before any inspection.
Identify each slot using the molded labels on the inner side of the cover. Colors indicate amperage, and numbers correspond to specific systems such as headlights, fuel pump, or interior electronics.
Test with a 12V meter before replacing any component. Replace only with parts matching the exact rating to prevent damage to wiring or connected modules. Avoid bypassing circuits to maintain electrical safety.
Maintain a reference log for modifications and replacements. Periodically inspect both enclosures for corrosion, moisture, or loose terminals, and wipe contacts with a dry cloth to ensure reliable operation of all vehicle systems.
Locating the Main and Secondary Panels
Access the primary cabin panel beneath the driver’s side dashboard near the footwell. Remove the lower trim carefully to reveal a rectangular enclosure secured with clips.
Inspect the engine compartment for a secondary panel on the passenger side near the battery. This section contains high-amperage connections for starter circuits, alternator, and cooling fans.
Use visible labels on the inner cover to identify circuits. Each slot is numbered, and color coding indicates amperage. Keep a flashlight handy to read markings in low-light conditions.
Check mounting and connections for both enclosures. Ensure all terminals are tight, free of corrosion, and correctly seated. Loose connections can trigger intermittent electrical faults.
The cabin panel controls circuits such as:
- Interior lighting and dashboard electronics
- Infotainment system and climate modules
- Power windows, locks, and mirrors
The engine compartment panel handles:
- Starter motor and alternator protection
- Cooling fans and fuel pump circuits
- High-load accessory relays
Maintain a reference sheet noting which slots correspond to specific systems. This simplifies future maintenance and prevents accidental replacement of components in the wrong location.
