Check the passenger-side kick panel first – the primary relay and circuit protection layout is positioned behind a removable trim, and accessing it requires only a flat screwdriver and careful pressure on the clips. Each slot corresponds to a specific electrical branch, including ignition, lighting, and audio systems, so identifying the correct position before replacement prevents short circuits and unnecessary component stress.
Under the hood, near the battery, sits a secondary power distribution unit responsible for high-load systems such as cooling fans and the charging circuit. This compartment uses higher amperage inserts, typically ranging from 30A to 80A, which differ significantly from the smaller cabin-installed elements. Always match amperage ratings precisely; installing a higher-rated piece risks wiring damage.
The interior panel uses a grid layout with clearly numbered slots arranged in rows. Common positions include: upper-left for dashboard illumination, central row for turn signals and brake lights, and lower section for accessory sockets. Cross-reference the numbering stamped into the plastic housing with a verified layout chart before making changes.
Corrosion and loose contacts are frequent causes of intermittent electrical failure in vehicles from this era. Inspect metal terminals for discoloration or residue, and clean gently using contact cleaner if needed. Secure seating of each component ensures consistent current flow and avoids flickering or sudden power loss.

Locate the interior panel under the driver-side dashboard and verify circuit labels before any testing; mismatched assumptions lead to incorrect diagnostics and wasted time. Use a flashlight to read worn markings, and compare amperage ratings stamped on each protective element with the service chart printed on the cover or manual.
Each slot corresponds to a specific circuit such as ignition, lighting, or ECU supply. Color coding and numeric ratings (for example, 10A red, 15A blue, 20A yellow) help distinguish load capacity. Never substitute a higher-rated component, as this removes protection and risks wiring damage. If a slot is empty, confirm whether it is unused or missing a link by checking adjacent labeling rather than guessing.
For quick identification, trace common problem areas: headlights often share a mid-range rating, while radio and interior electronics use lower values. A repeated failure in the same position indicates either a short to ground or a failing device on that circuit. Disconnect downstream components one by one to isolate the source rather than repeatedly replacing the protective link.
In the engine compartment, the secondary panel near the battery contains higher-capacity elements responsible for charging and cooling systems. Corrosion on terminals is frequent due to exposure; clean contacts with electrical cleaner and a soft brush, then re-seat firmly. Loose seating can mimic a blown component by interrupting current intermittently.
Use a multimeter set to continuity mode to confirm whether a link is intact. Touch probes to both terminals: a continuous tone or near-zero resistance confirms integrity, while no response indicates failure. Avoid relying solely on visual inspection, since micro-fractures in the metal strip may not be visible.
If multiple circuits fail simultaneously, inspect the main relay and grounding points rather than individual slots. A weak ground connection can cause erratic behavior across several systems. Tighten chassis grounds and inspect wiring harnesses for abrasion, especially near sharp edges or heat sources.
Keep a printed layout of both interior and engine-bay panels in the glove compartment; handwritten notes marking previous repairs or replacements save time during roadside diagnostics and reduce the risk of incorrect substitutions.
Locating and Accessing the Interior and Engine Bay Fuse Boxes in a 1992 Integra
Check the driver-side lower dash panel first: remove the small plastic cover just above the footwell to reveal the cabin electrical panel, positioned slightly left of the steering column. Use a flat trim tool or fingers to pull the cover outward; it is held by simple clips and does not require screws.
The interior unit sits behind a rectangular access door with a molded label showing circuit names; tilt your head upward from the pedal area to view it clearly. A flashlight helps identify individual slots and markings without removing surrounding panels.
To reach the under-hood power distribution unit, release the hood latch from inside the cabin and secure the hood with the prop rod. Stand on the left side of the engine bay (near the battery) where a black plastic housing is mounted close to the fender wall.
Press the side tabs on the engine compartment housing lid and lift it straight up; avoid prying with tools to prevent cracking the cover. Inside, you will find larger protective elements and relays arranged in rows, each labeled on the underside of the lid.
Interior access requires minimal disassembly, but if the lower trim obstructs your hand, remove two Phillips screws along the bottom edge of the knee panel and gently pull it back a few centimeters. This provides extra clearance without fully detaching the panel.
For the engine bay unit, inspect the surrounding wiring before touching anything; heat and vibration may loosen connectors over time. Keep the ignition off and remove the key to prevent accidental short circuits while working in this area.
Access Tips for Tight Spaces
Use long-nose pliers with insulated handles to grip small components in the cabin panel, as finger access is limited. In the engine compartment, a magnetic pickup tool can retrieve dropped parts that fall between the battery tray and chassis.
Verifying Correct Panel Locations
If unsure you have the right compartment, confirm by matching the visible labeling style: the cabin panel uses smaller text and grouped circuits, while the engine bay housing includes high-current protection elements and thicker wiring bundles. This visual difference helps avoid confusion during inspection or replacement.
