More about the product
The Aerpro APPIOPL Secondary ISO Harness with SWC is designed to make installing an aftermarket head unit simple while retaining factory steering wheel controls. This harness provides a secure and reliable connection between the new stereo and the vehicle’s wiring system, ensuring that essential features are maintained during the upgrade.
The APPIOPL harness works in conjunction with Aerpro’s primary ISO harness and steering wheel control interface. It is specifically engineered for vehicles that require a secondary ISO connection when replacing the factory stereo. By using this harness, installers can avoid cutting or splicing wires, which helps maintain the integrity of the vehicle’s original wiring and ensures a clean, professional finish.
One of the key advantages of the Aerpro APPIOPL is its ability to retain steering wheel audio controls. This means functions such as volume adjustment, track selection, and mode switching remain operational after the new head unit is installed. The harness is compatible with a wide range of aftermarket stereos that support steering wheel control integration, making it a versatile choice for many installations.
The harness features a plug-and-play design for quick and easy installation. It is constructed from high-quality materials to ensure durability and long-term reliability. The connectors are precision-made for a secure fit, reducing the risk of loose connections or signal loss. Its compact size allows it to fit neatly behind the dashboard without taking up unnecessary space.
Installation does not require specialised tools, but compatibility should always be confirmed before purchase. The APPIOPL is not a universal harness; it is designed for specific vehicle applications. For those seeking a professional installation that preserves factory features, this harness is an excellent solution.
