• Engine Family: D
• HP Range: 180-435 HP

Full model list at the end of this description.

⚙️ Key Features

• Sealed application-specific connectors
• Branch lengths follow the original engine routing
• Conductor sizes match circuit load
• Integrated shielding or twisted pairs where required
• Harness generation, ECU dataset and engine serial number must match
• Engine type: D13 electronically controlled marine diesel electrical system

🔌 Function

Connects the ECU, sensors, actuators and installation interfaces while protecting low-voltage signals from heat, oil, moisture and vibration.

⚠️ Common Signs of Failure

• Recurring electrical fault codes with no single failed component behind them
• Engine cutting out or derating over rough water
• Chafed or split outer sheath at a support point
• Water tracking into a connector, leaving corroded pins
• Broken or pulled-out terminal found when the connector is opened

🛠️ Service Notes

• This harness consolidates 21109100 and 40005272, listed earlier under names including a cable harness, a sensor kit and a flywheel housing, so check the branch layout against the engine before fitting
• Confirm the harness generation and ECU dataset match the engine serial number before ordering
