Use the manufacturer’s panel map to identify each circuit slot before touching any component. Check amperage ratings printed next to each position and match them strictly with the installed links–using a higher value can damage wiring, while a lower one may cause repeated outages. In compact coupes from the late 90s and early 2000s, this block is typically mounted near the driver’s knee area, slightly offset toward the center console.
Focus on labeling codes rather than color alone. Color can vary by supplier batches, but alphanumeric markings (for example “ACC”, “IGN”, “ECU”) correspond directly to specific subsystems such as accessory power, ignition circuit, or engine control unit. Cross-reference these codes with the service manual page dedicated to the interior relay board; this avoids confusion when multiple slots share similar hues.
Before inspection, disconnect the negative battery terminal and wait at least 60 seconds to prevent residual current flow. Use a multimeter to verify continuity instead of relying on visual inspection alone–microfractures in the metal strip are not always visible. If a circuit repeatedly fails, trace upstream components like relays or wiring harness connectors rather than replacing the same element multiple times.
For modifications such as adding aftermarket electronics, tap only into spare or designated accessory positions. Avoid piggyback connections on safety-related circuits like airbags or braking systems. Proper identification of each slot within this interior electrical block reduces diagnostic time and prevents costly electrical faults.
Integra Under Dash Fuse Diagram: Practical Guide
Locate the interior power distribution chart on the driver-side kick panel cover and verify amperage ratings before replacing any blown element; mismatching a 10A slot with a higher-rated insert risks wiring damage. Use a test light or multimeter to confirm continuity rather than relying on visual inspection, since micro-fractures in the metal strip are not always visible. Pay attention to circuit labels such as ECU, fuel pump, and accessory relay–misidentifying these can disable ignition or cause intermittent stalling. Keep a printed layout or a clear photo on your phone for quick reference during roadside checks.
Reading and Using the Layout Correctly
The interior panel map groups circuits by function, typically arranged in horizontal rows; left columns often handle lighting and signaling, while central slots connect to engine management and ignition systems. Cross-check numbering stamped on the plastic housing with the legend to avoid confusion caused by worn labels. If multiple electrical issues appear simultaneously–such as non-working radio and interior lights–inspect shared power lines indicated on the chart rather than replacing components individually. For recurring failures, trace the circuit path beyond the panel using wiring schematics, as repeated burnout usually points to a short or overloaded accessory rather than a defective insert.
How to Locate and Identify Each Fuse in the Integra Under Dash Panel
Open the driver-side lower trim panel and use a flashlight to read the labels stamped next to each slot; this panel sits directly beneath the steering column and is accessed by removing two plastic clips or a single screw depending on model year. Each circuit protector is arranged in horizontal rows, typically numbered from left to right. Match the numbering with the legend printed on the inner cover or in the owner’s manual to avoid confusion between similar amperage ratings.
Identify each component by amperage color coding and symbol markings. For example, 10A units are usually red, 15A blue, 20A yellow. Symbols beside each slot indicate the protected system such as headlights, fuel pump, or radio memory. Do not rely only on color–verify the printed number on top of each piece, as replacements may differ in shade.
Step-by-step identification
- Locate the row index (top, middle, bottom) using molded numbers on the plastic housing.
- Cross-check the slot number with the cover legend or service manual.
- Read the amperage value stamped on the component head.
- Confirm the circuit using icon or abbreviation (e.g., “ACC”, “IG”, “ECU”).
If the labeling is worn or missing, use a multimeter to trace continuity: remove one unit at a time and check which system loses power when ignition is in accessory or ON position. This method helps distinguish overlapping circuits such as interior lighting and accessory sockets that may share similar ratings but differ in activation state.
Common slot assignments
- Top-left: ignition switch feed (often 15A)
- Center row: HVAC blower and accessory relay links
- Lower section: interior lighting and clock backup (usually low amperage)
- Far right positions: optional equipment or unused reserves
