AC-T101 10pin・6pin Harness for Easy Installation of Aftermarket Audio in Toyota Vehicles

When installing aftermarket audio in a Toyota, people tend to focus on choosing the head unit and speakers. However, the harness used to connect to the vehicle side is also an important part that can significantly affect the final result.

AC-T101 is a 10pin・6pin harness for Toyota vehicles. It’s the type used for installing aftermarket audio in display-audio non-equipped vehicles and audio-less vehicles, such as the first-generation Aqua, 50-series Prius, and early C-HR. It also supports some Daihatsu models.

The reason to use this harness is that it allows you to proceed with the connection to the aftermarket audio without modifying the vehicle-side wiring more than necessary. Even if you later swap the audio unit or add components such as an amplifier or DSP, organizing the wiring makes it easier to review the work you’ve done.

The cable length is 1.8m. It’s a practical length that makes it easier to allow some slack for where the unit is installed and for routing the cables, and it’s also convenient if you want to neatly bundle the wiring on the rear side without pulling it forcefully. Even though it’s not visible, ensuring the wiring isn’t under strain is important for both maintenance and future system upgrades.

Also, if you plan to use it in a network mode dedicated to the front speakers, you will need separately added/modified wiring. Since the required content may vary depending on the vehicle model and your current audio configuration, it’s recommended not to decide only on the harness first, but to confirm everything together—including the equipment you’ll install and the system configuration you plan for the future.

At Logon, we guide you not only based on the harness compatibility on its own, but also by taking into account the specifications of the factory audio, the condition of the vehicle side, and even the direction of the sound you want to build. If I were doing it, I would organize the connection method properly at the very first stage so you don’t end up having to redo the wiring later.

If you’re considering aftermarket audio for a Toyota—or if you want to upgrade your system in a way that doesn’t place unnecessary strain on the factory setup—please consult us while checking the vehicle model, model year, and your current audio configuration.
