Installation Steps
- Access Factory Wiring: Carefully remove the necessary fairings and components to gain access to the factory radio and its wiring harness. Refer to your motorcycle's service manual for specific instructions on accessing these components.
- Disconnect Factory Harness: Locate and disconnect the factory wiring harness from the back of the radio.
