Plug & Play Integration Harness
An integration harness, also called SOT-harness, T-harness or Y-harness, is a convenient solution for connecting, for example, a DSP or high-to-low level converter without modifying the car’s original wiring. It acts as an extension of the car's original connector, where speaker and power cables are split into two ISO connectors.
One ISO connector provides a high-level signal and power supply for an audio processor, while the other ISO connector routes speaker cables out to the car and power back to the original system. This enables a smooth installation of audio processors and amplifiers without needing to run new cables or modify the car’s existing system.
