How to Install 2004 Honda Accord Auxiliary

To install a 2004 Honda Accord Auxiliary, prepare your workspace, adjust the shift knob, remove the plastic cover, unscrew from the shift knob area, work on the left compartment, disconnect the power outlet wire, install the auxiliary system, connect to the car radio, and finally, test and reassemble.


1. Preparations and Precautions

The initial phase, “Preparations and Precautions,” is critical to your Honda Accord aux installation process. To begin, the vehicle must be stationary and secure. This measure ensures it won’t move during the procedure, potentially causing damage or injury.

Turn off the engine and engage the emergency brake to render the vehicle immobile. In addition, remember to park the car in a well-lit and ventilated location for your comfort and visibility.

Next, focus on your toolkit. It’s crucial to assemble all the necessary equipment before commencing. You need a flat-blade screwdriver, a Phillips screwdriver, and long-nose pliers. Having all your tools in one place helps prevent interruptions once the process begins, ensuring a smoother, more efficient workflow.

Arrange your devices in a manner that is both accessible and orderly. This practice will save you time and reduce the risk of misplacing any of them during the operation.

The final element of this stage is a careful examination of your vehicle interior, particularly the console area. Familiarize yourself with the layout and identify the critical components discussed in the subsequent steps, such as the shift knob and its surrounding cover. This preparation will further streamline your efforts, making the following steps more intuitive and less daunting.

2. Shift Knob Adjustment

In the “Shift Knob Adjustment” phase, your objective is to create a clear path to the radio console in your Honda Accord. Start by pushing the shift knob to its farthest position, which in most automatic vehicles is the “1” or “L” slot. This repositioning offers more workspace, making the subsequent steps more manageable.

Knob of Car With Leather Cover

The small plastic cap next to the shift knob is your next target. This piece is typically firmly in place, requiring a flat-blade screwdriver to remove. Insert the blade carefully under the cap edge and gently pry it off. Care is essential here, as applying too much force can lead to damage to the cap or surrounding components.

You can access the shift knob’s inner section following the cap’s removal. Press down the uncovered inner part using the same flat-blade screwdriver and simultaneously pull back the shift knob.

Ensure a firm grip on the shift knob during this operation to avoid abrupt movements that could result in damage. The knob should now be in its farthest position, giving you the most space possible to proceed with the following steps.

3. Plastic Cover Removal

With the shift knob appropriately adjusted, you are now poised to commence “Plastic Cover Removal.” This stage requires finesse and patience. The cover you’re about to remove is securely attached in six different locations – two each on the back corners, the sides, and the front corners adjacent to the park “P” symbol. It is crucial to remember this distribution, as it aids in removing the cover without damaging it or the surrounding areas.

Equip your flat-blade screwdriver, your ally, for this operation. Use it to subtly pry between the plastic cover and the surrounding rectangular area. Apply steady upward pressure to disengage the mask from its points of attachment. The front corners, near the “P” symbol and one of the sides, are the ideal places to start this disengagement process. They tend to be the most accessible and can be ‘popped’ out with relative ease.

Once at least three of the attachment points are dislodged, the cover should be loose enough to be removed. Grasp it firmly and apply a reasonable amount of force. If it resists, check the other attachment points to ensure they’ve been adequately disengaged. The goal is a smooth removal, not a forceful extraction that could potentially damage the cover or its points of attachment.

4. Screw Removal from the Shift Knob Area

Moving forward, you now enter the “Screw Removal from the Shift Knob Area” stage. Your attention should focus on two corner screws found near the rectangular region where the shift knob resides. These screws, often overlooked, are integral to the console’s structure and must be carefully removed to access the radio system.

For this operation, you will need a Phillips screwdriver. Use it to unscrew the identified screws. Maintain a steady grip on the screwdriver, and apply force in a counter-clockwise direction. The screws should loosen and eventually disengage from their fixtures.

Long-nose pliers are the preferred tool to safely extract these screws. Pipe the loosened screws firmly with the pliers and gently pull them out. The long-nose design allows you to reach into the narrow space and retrieve the screws without dropping them into the wiring section – an issue that could complicate the entire process. Successful completion of this step paves the way for the following stages.

5. Compartment Work

In the “Compartment Work” stage, the focus is on the left compartment of your Honda Accord, specifically the rubber tray. This tray may seem innocuous, but removing it is key for the later stages of this project. This compartment is often used for storing small items and must be vacant for the operation ahead.

Deploy your flat-blade screwdriver once again, but this time, its task is not to pry but to assist in pushing. Lodge the blade in the seam of the tray until it is well positioned beneath the tray. Apply moderate force to lift the tray upwards, dislodging it from its original position. The objective is to get the tray out without causing damage to the compartment, so gentleness and patience are of the essence.

While pushing the tray out from underneath, grasp it firmly with your other hand and pull it steadily outwardly. In the case of resistance, try applying more force with the screwdriver while ensuring it does not scrape or damage the compartment’s edges.

6. Power Outlet Wire and Compartment Removal

Transitioning to the “Power Outlet Wire and Compartment Removal” stage, your attention now moves towards removing two sets of screws, a compartment, and the power outlet wire. These components, while essential for the regular functionality of your Honda Accord, need to be temporarily removed to install the aux input system.

Begin by unscrewing the identified screws with your Phillips screwdriver. Once loose, use your long-nose pliers to grip and extract them without falling into the wiring section. Every screw removal reduces the fastening strength of the compartment, making it easier to remove later.

Next, delicately disconnect the power outlet wire. Using your fingers to grip the connector rather than the cables is advised to prevent damage. Once the wire is disconnected, proceed to remove the remaining screws securing the largest compartment.

7. Auxiliary System Installation

Now, it’s time to delve into the heart of the “Auxiliary System Installation.” The path is paved for the new aux input system after clearing out the necessary space. The main task here is to correctly position and route the aux wire, the lifeline of your new audio system.

Technician While Installment The Auxiliary System

Start by taking hold of the auxiliary wire. Note its two ends: one is designed to connect to the audio system (often featuring a unique connector or group of cables), and the other is a standard aux port for plugging in your devices. Make sure to identify these correctly to avoid any confusion during the installation.

The route of the aux wire is critical. It should run behind the glove compartment and into the wiring section of the console. This pathway ensures the wire is kept from moving components that might damage it and gives your installation a clean, professional finish. Route the wire carefully, avoiding sharp bends or twists, which could impair the wire’s performance.

Finally, position the aux port in a location that’s easy to reach but won’t interfere with the vehicle’s operations. Depending on your preference, you may choose to have it protruding slightly for easier access or hidden away for a more streamlined look.

8. Connection to the Car Radio

The climax of your installation is the “Connection to the Car Radio.” This is where the aux input system integrates with your Honda Accord’s existing audio setup. The aim is to establish a reliable and efficient link between the aux system and the car radio to ensure the best possible audio output.

Connecting The New Sound System to The Car Radio

Identify the white piece beneath the car radio. This is the target connector for the aux input wire. It is typically a multi-pin connector designed to receive various inputs to the radio. Plug in the auxiliary wire firmly, ensuring a solid and secure connection. A loose or half-connected wire can lead to inconsistent sound or, in some cases, no sound at all.

Always ensure the connection is made to the correct port. Misconnections can lead to non-functionality of the aux system or, worse, damage to the car radio. A correctly connected system should integrate seamlessly with your Honda Civic or Accord’s existing audio setup, ready to deliver high-quality audio from your auxiliary devices.

9. Testing and Reassembly

The final phase, “Testing and Reassembly,” is your opportunity to verify the functionality of your new aux input system and restore your Honda Accord to its pristine condition. This stage ensures the aux port works as expected and that all previously disassembled components are correctly reinstalled.

Testing The New Sound System On Car

Commence by turning on the car ignition. Navigate the car radio to the aux setting; the exact method may vary depending on the model of your radio. Plug a device, such as a phone or an MP3 player, into the newly installed aux port and play some music. Listen for clear, undistorted audio. The successful sound output verifies the correct installation and functionality of the aux system.

In case of any sound issues, check the connections between the auxiliary wire and the car radio. Make sure the wire is inserted correctly, and the connection is secure. If the problem persists, you may need to inspect the auxiliary wire for any possible damage or incorrect routing.

Once you’ve verified that the aux system works properly, start the reassembly. Begin by returning the largest compartment to its place and reattaching the power outlet wire. Then, carefully reinstall the screws to secure the compartment. Remember to replace the rubber tray in the left chamber as well.


In closing, mastering the 2004 Honda Accord Auxiliary system installation is more achievable than you may think. Summing up the key concepts we’ve covered:

  • Start with the proper preparations and precautions, ensuring safety and readiness and adjust the shift knob and carefully remove the plastic cover around it.
