Locate the primary electrical panel under the dashboard on the driver’s side. Remove the protective lid by pressing the release tabs on either side. The labeling inside provides exact amperage ratings for each circuit, including headlights, horn, and power windows.
Identify each slot before attempting replacements. Circuits are numbered and correspond to the layout printed on the inside of the lid. Using the printed chart ensures that each miniature circuit breaker or blade type component is restored to its designated position without overloading any system.
Check continuity with a multimeter before reinstalling any protective components. This prevents repeated interruptions in electrical supply and avoids damage to wiring harnesses. Make sure connectors are seated firmly, and inspect for corrosion or discoloration at each terminal.
Label the lid clearly if markings have faded over time. A simple color-coded or numerical annotation improves future troubleshooting and reduces the risk of inserting a component in the wrong slot, which can trip circuits or create minor shorts.
Electrical Panel Layout for 1994 Acura Integra

Access the main junction box under the steering column by releasing the clips on both sides. This panel holds all the miniature circuit holders controlling lights, ignition, audio, and climate components. Each slot is numbered and matches the schematic printed inside the lid.
Verify the amperage rating before swapping any component. Standard slots use 10A, 15A, or 20A inserts, while larger circuits like the rear defroster and ABS pump require 30A. Installing a lower or higher rated component can trigger electrical faults or cause wire overheating.
Observe the orientation of each blade. Certain circuits, including the horn relay and fuel pump, are polarized; reversing their terminals can prevent operation or create intermittent issues. The inside legend provides both position and polarity cues.
Keep a spare set of miniature breakers in the glove compartment. This allows immediate replacement of critical circuits such as headlights or engine management, minimizing downtime. Check each spare for corrosion or bent prongs before storing.
Routine Inspection Tips

Examine terminals for discoloration or loose connections. Heat spots indicate overcurrent history, signaling a need for wiring inspection. Tighten retaining clips gently without overcompressing to avoid plastic deformation.
Use a multimeter to confirm continuity before reseating any circuit insert. Measure across both sides of the slot to ensure proper current flow. This prevents repeated trips and protects sensitive electronics like the ECU and dashboard sensors.
Marking and Maintenance
Label the inside schematic if numbers have faded. Use a small, durable sticker or fine-point pen resistant to oils and temperature changes. Clear markings save time during troubleshooting and ensure each miniature component returns to its original location.
Locating the Electrical Panel and Identifying the Lid
Access the junction box under the driver’s side dashboard. It is positioned just above the pedals, secured with two snap clips on either edge. Remove the panel gently to avoid cracking the housing. The interior side of the lid shows the slot layout for circuits controlling:
- Headlights and taillights
- Horn and turn signals
- Ignition system and ECU connections
- Climate control and blower motors
- Audio and accessory power outlets
Confirm the panel type before attempting replacements. Plastic lids may vary between early and late production runs. Check for printed numbers and amperage ratings on the inner surface. If markings are worn, trace circuits with a multimeter to prevent installing an insert in the wrong slot, which can interrupt power or damage wiring harnesses.
