The Connects2 ISO-T SOT harness provides a plug-and-play interface between Toyota factory wiring and aftermarket amplifiers or Bluetooth handsfree kits. It accepts high-level speaker outputs and passes them through the amplifier to the speakers without cutting factory wires.

Built with OEM-specific ISO connections, the harness supplies power and earth connections required by many handsfree kits and channels phone audio through the front speakers. Compatibility covers multiple Toyota models; verify the vehicle connector matches the harness prior to purchase.
