Audio Connection Harness for Honda Cars AC-H242 24-pin with Lock 1.8m

You want to install an aftermarket audio system in your Honda, but you don’t want to damage the factory wiring as much as possible.
That’s where AddOn AC-H242 comes in as a solid foundation.

This model is a 1.8m harness that uses a 24-pin lockable connector for Honda.
It’s designed to make it easier to connect without significantly disturbing the factory-side wiring, and to streamline wiring work during installation. Although it’s an unseen component, the way you choose a harness like this can surprisingly affect the reliability of the work and the neatness of the finished result.

A harness that suits those who want to proceed without cutting wires

“I want to keep the factory condition as much as possible.”
“There’s a chance I may change the configuration later.”
For people like that, using a dedicated harness for the connection is a very compatible approach.

Thanks to the 1.8m length, there’s typically more room for routing, and wiring work around the head unit becomes less strained.
In addition, the 24-pin with lock mechanism lets you secure the connection firmly, helping reduce the risk of poor contact and making it easier to achieve a clean, well-managed wiring layout.

Sound quality differences start with details like these

It’s not a part that directly changes sound like speakers or DSP, but creating a stable connection environment is the foundation of any audio installation.
If the base is left ambiguous, even if you carefully choose and fine-tune the equipment that comes next, it can affect how well the whole system comes together.

At Logon as well, we consider such peripheral parts not just as consumables, but as components chosen by taking into account compatibility with the vehicle and even how the system may evolve in the future.
Because they’re not visually prominent, if you organize them properly—including routing, securing, and restoring them—it will pay off later.

Recommended for people like you

• Those who want to introduce an aftermarket audio system in a Honda
• Those who want to install while modifying the factory wiring as little as possible
• Those who want more flexibility for cable routing
• Those who want to build it neatly with future system upgrades in mind

Also note that if you use it in a front-speaker-only network mode, additional加工/wiring work is required.
Because what’s needed varies depending on how you use it, even if your system configuration isn’t decided yet, sorting things out in advance will make the process smoother.

It’s not a flashy part, but choosing components like this carefully can significantly change the peace of mind after installation.
If you want to assemble your Honda’s audio system smoothly and comfortably, we recommend starting by thinking carefully about harness selection like this.
