For anyone modifying or upgrading vehicle electrical systems, being able to place a controller box where it’s most accessible—without compromising the wiring integrity—is a real advantage. This extension keeps your original wiring intact, eliminating the need to splice or surgically alter existing cables. The result is a cleaner install, fewer potential failure points, and easier maintenance down the line.

Ideal use cases

Whether you’re outfitting UTVs, trucks, trailers, buses, motorhomes, or establishing a long‑distance parking‑aid system, this 20-foot extension gives you the flexibility to run cables to the most convenient location. It’s especially useful when the control panel needs to be mounted away from the power source or where a tidy, unobtrusive wiring route is preferred.

What’s included

1 x extended line. Note: due to manual measurement, a 1–3 cm difference is possible. Color and shade may vary slightly due to lighting and display settings.

Practical installation tips

Plan your route to avoid sharp bends, keep the extension clear of high-heat areas, and verify DC voltage compatibility before installation. With the compatible 4-pin connector, you can quickly connect cameras, displays, or other peripherals to extend control and monitoring capabilities across your vehicle setup.

Compatibility and installation confidence you can rely on — all wrapped in a 20‑foot solution designed for serious vehicle electronics modification.
