CAC HEXT1.5M ISO Canbus Extension Cable Harness 1.5 Metre

CAC HEXT1.5M ISO Canbus Extension Cable Harness 1.5 Metre

A 1.5 metre ISO Canbus extension cable harness providing the additional wiring length needed for clean and flexible head unit installations across compatible Holden, Volkswagen, and Iveco vehicles.

Product Overview

The HEXT1.5M is a 1.5 metre ISO Canbus extension cable harness designed to extend the reach between a vehicle's factory wiring and an aftermarket head unit installation. In many modern vehicles, particularly those with integrated Canbus systems, the factory wiring does not provide enough slack to accommodate flexible head unit positioning or routing through the dashboard cleanly. The HEXT1.5M bridges this gap with an additional 1.5 metres of cable length, ensuring a tidy and professional installation without the need for makeshift wiring extensions or compromises to cable management.

Compatible with the Holden Astra BK (2016-2020), Volkswagen Golf MK7 (2013-2016), Volkswagen Golf (2017-2020, Dash 1 and Dash 2), Volkswagen Polo (2015-2017), and Iveco selected models, the HEXT1.5M is a practical addition to any compatible vehicle head unit installation toolkit, particularly when routing cables through tight or complex dashboard configurations.

Features & Benefits

1.5 Metre Extension Length: Provides a generous 1.5 metres of additional cable length, giving installers the flexibility to route wiring cleanly through the dashboard without pulling, stretching, or creating stress points on the factory harness connections.

ISO Canbus Compatible: Built to work with ISO Canbus wiring configurations found in compatible Holden, Volkswagen, and Iveco vehicles, ensuring reliable signal integrity and proper communication between the vehicle's Canbus system and the aftermarket head unit.

Plug and Play Design: Connects directly between the factory vehicle wiring and the head unit harness with no cutting or splicing required, making it straightforward to install and just as easy to remove if needed.

Clean Installation Solution: Eliminates the need for improvised cable extensions during head unit installations in vehicles where the factory loom does not reach, supporting a professional finish and reducing the risk of loose or unreliable wiring connections.

Frequently Asked Questions

What is the purpose of the HEXT1.5M extension harness?

The HEXT1.5M is used to extend the reach of the ISO Canbus wiring connection between a vehicle's factory harness and an aftermarket head unit. It is particularly useful in vehicles where the factory loom is too short to allow clean cable routing through the dashboard, providing an additional 1.5 metres of length for a neat and professional installation.

Does the HEXT1.5M work as a standalone installation harness?

No. The HEXT1.5M is an extension cable only and must be used in conjunction with the appropriate vehicle-specific wiring harness for your make and model. It does not replace a primary harness and does not provide SWC, camera, USB, or antenna retention on its own.

Will using an extension cable affect Canbus signal quality?

The HEXT1.5M is engineered to maintain ISO Canbus signal integrity over the 1.5 metre extension length. Provided it is used with a correctly matched primary harness and a compatible head unit, signal quality and Canbus communication should not be adversely affected.

Is the HEXT1.5M compatible with all Volkswagen Golf models?

No. The HEXT1.5M is confirmed compatible with the Volkswagen Golf MK7 (2013-2016) and the Volkswagen Golf (2017-2020, Dash 1 and Dash 2) only. It is not listed as compatible with earlier or later Golf variants. For other Golf model years, please contact our team to confirm the correct extension or harness for your vehicle.

Is professional installation recommended when using the HEXT1.5M?

While the HEXT1.5M is a plug-and-play component, professional installation by a qualified car audio technician is always recommended, particularly in Canbus-equipped vehicles where incorrect connections can affect vehicle electronics. A professional installer will ensure the extension is correctly integrated into the wiring system and that all functions are operating as expected.
