• Engine Family: D
• HP Range: 13-435 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
• Also supersedes Volvo part numbers 3583725, 3583873 and 3818550

🔌 Function

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

⚠️ Common Signs of Failure

• Signal dropping out on one circuit while everything else works normally
• Fault codes that follow the connector rather than the component
• Insulation rubbed shiny or split at a routing point
• Corrosion visible in the connector when unplugged
• Terminal backed out of its housing, or a broken lock, found on strip-down

🛠️ Service Notes

• This part replaces 21138559, 21140575 and 3587360, previously catalogued under flywheel housing and sensor kit names, so verify the connector population against the installation
• Check the mating component connector for pushed-back or spread terminals at the same time
