Full model list at the end of this description.

⚙️ Key Features

• Factory connector keying, pin allocation and branch lengths
• Wire gauges and shielding matched to the assigned circuits
• Protective sleeving designed for engine heat, oil and vibration
• Correct breakout points prevent strain at sensors and actuators
• Product number, serial number and control-system generation must match

🔌 Function

Distributes power, ground and control signals between the D3 ECU, sensors, actuators and vessel interface.

⚠️ Common Signs of Failure

• Engine faults that come and go with vibration or when the loom is flexed
• Several unrelated codes stored together, pointing at the harness rather than one sensor
• Corrosion or moisture in the relay box or an engine-side connector
• Insulation chafed through where a branch crosses a bracket or clip
• Terminals pushed back in a housing so a circuit reads open when the engine is running

🛠️ Service Notes

• The listed weight of 0.082 kg sits far below the other main engine harnesses in this listing, such as 21879108 at 3.81 kg, so do not use weight to identify it - order by part number and engine generation
• Check the relay box, the earths and the individual circuit before committing to a harness replacement
