Locate the primary electrical panel behind the driver’s side kick panel under the dashboard. Remove the securing screws and carefully pull the cover to expose the array of circuits. Keep a small flashlight handy for clear visibility of labels and ratings.
Each slot is assigned to a specific circuit, including lighting, ignition, and accessory controls. Check the amperage ratings printed on the top edge before attempting any replacement to prevent overloading or short circuits.
Panel removal requires minimal tools: a Phillips screwdriver and a pair of needle-nose pliers for accessing clips. Disconnect the negative battery terminal to eliminate the risk of sparks while inspecting or swapping components.
Regular inspection of this panel can prevent intermittent electrical issues that affect headlights, wipers, and cabin accessories. Document any changes with a simple sketch or label for future reference, ensuring correct placement during reassembly.
1989 LX Sedan Electrical Panel Reference
Access the primary electrical panel by removing the lower dash cover on the driver’s side. Undo the three retaining screws and gently pull the cover to reveal all circuit slots and connectors.
The panel is divided into two sections: high-amperage circuits for ignition and headlights, and low-amperage circuits for cabin accessories and indicators. Label each component before removal to prevent misplacement.
High-amperage circuits are positioned on the left side and include:
- Ignition system
- Main headlights
- Rear defroster
- Radiator fan control
Low-amperage circuits on the right side control smaller systems:
- Interior lighting
- Audio and radio
- Turn signals and hazard lights
- Power mirrors and accessory outlets
Each slot has an embossed rating number for amperage. Check these values before installing a replacement to avoid electrical overload or damage.
Panel connectors are keyed to prevent incorrect insertion. Use a small flathead to release clips and pull connectors straight out. Do not force them to avoid bending terminals.
Routine inspection of this panel can identify worn contacts or corroded terminals early. Apply dielectric grease to connections for improved conductivity and to extend service life of the electrical components.
Identifying Each Circuit and Its Function in the LX
Start by referencing the labeling on the driver-side panel. Each slot corresponds to a specific electrical path, including ignition, lighting, and auxiliary systems. Verify each component before handling to prevent accidental shorts.
Primary circuits for engine operation include the starter relay, ignition coil, and fuel pump. Check the rating numbers stamped beside each slot to match replacement elements accurately and maintain system integrity.
Lighting and signaling circuits are grouped separately. Headlamps, turn indicators, brake lights, and interior lamps occupy dedicated channels to isolate faults and simplify troubleshooting. Follow the color-coded wiring harness for easier identification.
Accessory circuits include the radio, heater fan, power mirrors, and cigarette lighter. Test each slot with a multimeter before replacing components to confirm the specific path and prevent misconnection.
Keep a printed reference or a photo of the panel layout after identifying each path. Documenting amperage and location helps with future repairs and ensures that replacements maintain proper circuit protection and system reliability.
