Fusion Wire Harness f/MS-SRX400 Stereo (D Port)

The Fusion Wire Harness for MS-SRX400 Stereo (D Port) is a dedicated power, speaker, and RCA cable assembly engineered for seamless integration with Fusion's MS-SRX400 marine stereo system. This OEM harness eliminates guesswork during installation by providing factory-correct connectors and pinout configuration, ensuring reliable audio and power delivery without compatibility issues or adapter workarounds.

The D Port connector standard ensures proper fit and function with the MS-SRX400's marine-grade architecture. This harness handles combined power input, speaker output, and auxiliary audio connections in a single integrated cable run, reducing installation complexity and potential failure points common to field-pieced wiring. The compact 4 x 1 x 6-inch profile allows straightforward routing through confined spaces typical of marine installations, whether in center consoles, cabin bulkheads, or engine compartments where space is at a premium.

Users installing or upgrading a Fusion MS-SRX400 system rely on this harness to maintain OEM electrical integrity and audio fidelity. Replacement scenarios include damaged original harnesses, multi-unit setups requiring additional harness runs, or system expansions adding secondary zone amplification. Fusion's marine electronics are built to withstand saltwater environments, UV exposure, and vibration—this harness meets those same durability standards as a factory component.

Part number 010-12814-00 is the authoritative reference for compatibility verification. Confirm your stereo model is MS-SRX400 and features a D Port connector before ordering to avoid mismatch. This is a direct replacement or supplemental harness—not a universal adapter.
