Our ISO-T Harness SOT lead is a practical solution for adding an aftermarket amplifier, Bluetooth car kit or hands-free kit to vehicles with the new style large connector behind the radio. Fitted between the vehicle and the original radio connection, it helps create a cleaner installation without invasive cable cutting, preserving the integrity of the factory wiring loom.

When used for an aftermarket amplifier installation, the harness takes the high-level input signal from the vehicle, routes it through the amplifier and then sends the amplified signal on to the speakers. This makes it a useful choice for audio upgrades where you want to keep the installation tidy and vehicle-specific while avoiding unnecessary wiring modifications.

The SOT harness is also ideal for Bluetooth car kits and hands-free kits. Installed behind the radio as a break-out cable, it supplies the power and earth connections needed for the kit and routes phone audio through the front speakers of the vehicle for seamless integration. It is designed for use with kits that include an ISO mute harness, including popular Parrot, Bury, Nokia and Motorola systems.
