2014-2023 Harley Davidson Break Out Harness for MSHD14

The HDTSR14 Breakout Harness from Diamond Audio is engineered to unlock the full potential of the MSHD14 receiver by expanding its output capabilities for advanced motorcycle audio systems. Designed specifically for applications requiring more than the standard six low-level outputs, this harness adds  4 channels of 5V RCA outputs, allowing installers to fully utilize a total of 10 DSP channels built into the receiver.

The HDTSR14 connects directly to the MSHD14 using factory-style connectors, eliminating the need for re-pinning, cutting, or modifying the OEM harness. A built-in “T” split design provides four additional RCA outputs when extra amplifier channels are required, making it ideal for complex multi-amplifier or multi-speaker Harley-Davidson® audio builds.

This signal input/output harness includes four additional RCA connectors for seamless amplifier integration, along with an output speaker wire harness for added flexibility. Please note that the RCA outputs carry a high-level signal, so amplifiers must support high-level input through RCA connections.

Built for clean integration, scalability, and professional installation, the HDTSR14 is the essential solution for expanding and optimizing your MSHD14-powered audio system.
