【Front Door Wiring-Harness Coupler Vehicle Additional Installation｜A Service Menu for Safely Adding Wiring Inside the Door】

Front Door Wiring-Harness Coupler Vehicle Additional Installation is a procedure designed to add new wiring inside the door while achieving both safety and a high-quality finish as much as possible.
In many recent vehicles, a genuine coupler is used between the door and the body, making the way the wiring is routed more important than it may seem at first glance. If this step is handled carelessly, it can lead to broken wires, poor contact, and troubles later on.

At Log On, we add wiring using routes that place no undue strain, while checking the structure unique to each vehicle.
Not only do we run the wiring, but by finishing it while also considering interference with genuine parts and how everything moves, it becomes easier to proceed with door-area work with confidence—such as speaker replacement, adding an amplifier, and deadening.

In particular, handling of parts that can’t be seen has a major impact on how satisfied you’ll feel after completion.
Although this kind of work is difficult to notice from the outside, when the foundation is done properly, it leads to peace of mind during long-term use and also contributes to the overall sound quality. It’s also suitable for those who want to add wiring in a natural form without significantly altering the original, factory look and feel.

“I want to avoid issues that may show up later.”
“I want to organize the wiring work inside the door neatly.”
If that sounds like you, we can proceed according to the condition of your vehicle—so please feel free to consult us first. While looking at the actual car, we’ll organize the necessary details and guide you accordingly.
