Access the main control module beneath the dashboard on the driver’s side by removing the retaining screws and sliding the cover forward. Handle all wiring harnesses carefully to prevent connector damage.
Identify each circuit by its color and shape. Red wires carry constant battery power, brown wires serve as ground, blue wires control headlights, and yellow wires feed auxiliary components. Proper identification prevents accidental shorts and miswiring.
Inspect terminals for corrosion or loose connections when the module is exposed. Use a small wire brush or electronic contact cleaner to remove oxidation. Ensure each connector is fully seated before reassembling the cover.
Label any aftermarket additions before reconnecting power. Route new wires to auxiliary slots and secure them away from sharp edges or moving parts to maintain long-term reliability.
1995 Geo Metro Electrical Panel Reference
Access the central control module under the driver’s side dash by removing the securing screws and sliding the cover forward. Avoid pulling on wiring harnesses to prevent connector damage.
Identify each slot by shape and color coding. Red wires carry battery power, brown wires act as ground, blue wires operate high beams, and yellow wires control auxiliary circuits. Correct identification ensures safe handling and prevents shorts.
Inspect terminals for corrosion or loose pins while the panel is exposed. Light oxidation can be cleaned with a small wire brush or electronic contact cleaner to maintain conductivity.
Slot 1 controls main headlamp circuits, slot 2 governs turn signals and hazard lights, and slot 3 powers the horn relay. Slot 4 handles dashboard illumination and courtesy lights, while slot 5 feeds the ignition relay.
Slot 6 provides power to the audio system, slot 7 manages brake and tail light circuits, and slot 8 supplies accessory outlets and the cigarette lighter. Verify each connection before restoring power to avoid intermittent faults.
Label any aftermarket wiring before reinstallation. Route new leads to auxiliary slots and secure them away from sharp edges or moving components to prevent wear or pinching.
Test continuity of all circuits with a multimeter before reconnecting the battery. Ensure all connectors are fully seated and the cover is properly secured to protect terminals from moisture and dust.
Locating the Main Control Module
Slide under the driver’s side dashboard and look above the kick panel for a rectangular plastic module secured with screws on both sides. Remove the cover carefully to expose terminals.
Trace wiring harnesses from the ignition switch and steering column to quickly identify the module. All primary circuits including headlights, brake lights, and auxiliary power converge at this location.
- Locate mounting screws and clips securing the module.
- Disconnect the battery before touching connectors.
- Inspect wires for wear or corrosion before removal.
- Use a flashlight to see tight terminal connections clearly.
After inspection, reattach the module securely and confirm that all connectors are fully seated. Test key circuits such as lighting, horn, and dashboard indicators before reinstalling trim panels.
