To properly inspect or replace any electrical components in your vehicle, it’s crucial to first locate the panel controlling the vehicle’s electrical circuits. In this model, the central panel can be found either under the dashboard near the driver’s side or within the engine compartment. The location may differ based on the specific configuration, but these two areas are the most common.
Once you find the panel, it’s important to understand the arrangement of its components. The layout typically features numbered slots for relays and wiring, clearly indicating which circuit each component controls. These markings are essential for quick identification, ensuring you can resolve electrical issues without confusion or mistakes.
To avoid damaging the vehicle’s electrical system during repairs, always consult the vehicle’s manual before proceeding. This will give you the precise location of each part within the control panel, as well as any instructions specific to the vehicle’s design. Familiarizing yourself with these details will streamline troubleshooting and maintenance tasks significantly.

The primary control panel for the vehicle’s electrical system is typically located under the dashboard near the driver’s seat. You can access it by removing a cover or panel, which is usually secured by clips or screws. This unit houses multiple circuits for components like lights, air conditioning, and wipers.
If you do not find it in the driver’s area, check the engine compartment. Many vehicles place a secondary control unit here to manage high-voltage systems like the battery and alternator. The cover is often labeled and should be easily removable with a small screwdriver or by unclipping it.
Understanding the Layout
Once you’ve located the control unit, it is important to familiarize yourself with its layout. The wiring connections are usually numbered and color-coded for easier identification. Each section is dedicated to specific components, such as lighting, ignition, and entertainment systems. The manual will indicate which section corresponds to each component, preventing confusion during repairs.
Some models also have auxiliary control units inside the cabin or near the rear seats. These are generally more compact and deal with minor components. While not always mentioned in the manual, checking behind the seats or in the boot could reveal additional units that manage things like the power windows or mirrors.
Replacing a Damaged Unit
If you discover any component inside the control panel that needs replacing, first ensure the vehicle is off and the key is removed. Use the layout guide to identify the exact position of the faulty part. Carefully replace the unit, making sure the connections are properly secured to avoid any electrical issues.
Regularly inspecting the control unit is recommended to prevent major electrical failures. Over time, connections can become loose or corroded, affecting the vehicle’s overall functionality. Checking the wiring annually and cleaning any corrosion ensures the longevity of the electrical components and reduces the risk of malfunctions.
Locating the Electrical Panel in the 2006 Infiniti FX35
The main electrical unit in your vehicle is typically found beneath the dashboard near the driver’s side. To access it, look under the steering column or near the footwell. You may need to remove a cover, which can be secured with clips or screws. This compartment contains circuits for various systems such as lights, wipers, and HVAC.
If you can’t find the unit in the driver’s area, check the engine compartment. The panel here often handles high-voltage components, such as the alternator and battery. Look near the battery or along the left side of the engine bay for a rectangular cover, which can usually be unclipped or unscrewed for easy access.
- Look under the driver’s side dashboard near the pedals for the first unit.
- Check the engine compartment for a second unit managing high-voltage systems.
- In some models, there may be smaller units behind the rear seats or in the trunk area.
When locating the electrical unit in the engine compartment, make sure to inspect the area carefully. Some models use a plastic shield or a cover that must be removed before you can access the components. Use a flashlight to identify any unlabeled parts, especially if they are hidden behind other engine components like the air filter or coolant reservoir.
For those models with additional panels, such as near the glove compartment or in the rear seating area, remove any trim or carpet covers to gain access. These panels typically house relays for auxiliary systems like power windows and mirrors. While not always directly referenced in the vehicle manual, knowing where to look will save time during maintenance.
Always refer to the vehicle’s manual for guidance. The manual will provide you with the exact location and layout for the control unit based on your model variant. It may also offer a guide on how to safely remove covers or panels to avoid damaging internal components.
Once located, check for clear markings on each component to help identify which circuits are connected to specific vehicle systems. If necessary, use the manual’s layout guide to ensure you’re working with the correct part of the electrical system, especially when replacing damaged parts or conducting repairs.
