The compact sedan’s wiring system relies on two main distribution units: one installed beneath the steering column and another positioned in the engine compartment near the battery. Each unit contains multiple protective elements with clearly defined amperage values, typically ranging from 7.5A to 40A. Matching the correct rating is mandatory, as installing a higher-rated element can damage sensitive electronics such as the infotainment module or electronic steering control.
Interior panel layout usually includes slots assigned to lighting circuits, audio system, climate control, and diagnostic connector. For example, the slot responsible for the accessory power outlet is commonly rated at 20A, while memory systems and onboard computer lines often use 7.5A protection. Labels are printed on the reverse side of the panel cover, allowing quick identification without removing multiple components.
Engine compartment distribution unit handles high-load systems such as radiator fan, anti-lock braking system, and ignition coils. These positions typically use higher amperage elements, such as 30A or 40A. A visual inspection should always include checking for discoloration or melted plastic around terminals, which indicates overheating or poor contact.
For accurate troubleshooting, use a multimeter to confirm continuity instead of relying solely on visual inspection. A broken internal strip may not always be visible. Keeping a small set of spare elements with varied ratings in the glove compartment reduces downtime and prevents incorrect substitutions during roadside repairs.

Check the passenger-side panel first: remove the trim near the glove compartment to access the primary circuit layout, then compare each slot with the legend printed on the cover to avoid pulling the wrong safety element.
The cabin electrical panel contains most low-amperage protection points for interior systems such as infotainment, climate control, and lighting. Typical ratings range from 7.5A to 20A, and each position is labeled with a short code. Match these codes with the reference chart to identify circuits quickly.
Under the hood, a separate power distribution unit handles higher loads. This area includes protection for engine control modules, cooling fans, and charging systems. Ratings here often exceed 30A, and some slots use square-shaped high-current components instead of the smaller blade type found inside.
Common slot assignments include:
- Audio system – 15A
- Power windows – 20A
- Brake lights – 10A
- Fuel pump – 15A
- ABS module – 30A
If a circuit fails, inspect the metal strip inside the protective piece. A broken or darkened strip signals overload. Replace only with the same amperage; using a higher rating risks wiring damage or fire.
Access to the engine compartment unit usually requires releasing two plastic clips on the cover. Inside, a molded map shows component positions. Keep the cover clean and secured tightly to prevent moisture from affecting contacts.
For repeated failures in the same slot, avoid simply swapping parts. Trace the connected system: wiring harness damage, faulty relays, or shorted devices often cause recurring issues. A multimeter helps confirm continuity and voltage before inserting a new protector.
Store spare blade-style protectors (7.5A, 10A, 15A, 20A) in the glove compartment along with a puller tool. This reduces downtime during roadside troubleshooting and prevents using incorrect substitutes.
Exact Location of Interior and Engine Bay Fuse Boxes in the 2014 Acura ILX
Open the driver’s door and inspect the lower left section of the dashboard: the interior electrical panel sits behind a small rectangular cover directly beneath the steering column. Pull the cover outward using the molded notch; no tools are required. This panel is positioned slightly above the footwell trim, making it accessible without removing additional components.
For better visibility, slide the driver’s seat fully back and use a flashlight to identify the rows of mini blade fuses. The layout is arranged in horizontal lines, with labels printed on the inner side of the cover. A plastic puller is clipped inside, designed specifically for safe removal of individual elements without damaging surrounding connectors.
The under-hood power distribution unit is located on the right-hand side of the engine compartment (passenger side for left-hand drive vehicles). Look near the battery housing: a black rectangular enclosure with a snap-on lid. Release the two side clips by pressing inward, then lift the lid upward to expose high-amperage circuits and relays.
Access clearance in the engine compartment is limited by intake tubing and wiring harnesses, so approach from the front corner of the vehicle. Keep the engine off and cool before opening the enclosure to avoid contact with heated components. The lid underside contains a printed map showing circuit assignments and amperage ratings.
Interior and engine compartment panels serve different systems: cabin electronics such as audio, lighting, and accessory sockets are routed through the dashboard unit, while ignition, cooling fans, and ABS are handled by the engine-side distribution center. Mixing them up during troubleshooting leads to incorrect checks and wasted time.
Tip: always verify amperage markings before replacing any blown element. Installing a higher-rated piece risks wiring damage. Keep spare mini and low-profile fuses in the glove compartment to avoid roadside delays when a circuit fails unexpectedly.
