What Is An ISO Harness?.
ISO Harnesses: The Ultimate Guide for Beginners
Introduction
ISO harnesses are a type of wiring harness that is used to connect an aftermarket head unit to a car's factory wiring system. They are standardized, meaning that any head unit with ISO connectors will be compatible with any ISO harness. This makes them a simple and easy way to install a new head unit in your car, without having to cut or splice any wires.
ISO harnesses are typically made up of two connectors: a black connector for power and ground, and a brown connector for speakers. The black connector has eight pins, while the brown connector has six pins. Each pin is assigned a specific function, such as power, ground, left front speaker, right front speaker, left rear speaker, and right rear speaker.
