1078054 Wiring Harness | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta wiring-harness repair lead used to service damaged engine-control-module connector wiring on selected EMS and EMS 2 industrial diesel engines. Volvo workshop literature identifies 1078054 as the repair harness used when replacing damaged terminals or short connector leads rather than replacing the complete engine harness.

🚤 Compatibility

• Year Range: Approximately 2000s-2010s

⚙️ Key Features

• Genuine Volvo Penta OEM wiring-harness repair kit
• Correct Volvo Penta part number 1078054
• Used for engine-control-unit connector and harness repairs
• Supports correct terminal sealing and conductor specification
• Applicable to selected 9-, 12- and 16-litre EMS engine families
• Engine type: Volvo Penta electronically controlled industrial and generator diesel
• System type: EMS / EMS 2 engine-control wiring repair

🔌 Function

The repair harness restores the electrical connection between the engine wiring loom and control-unit connector. Correct conductor size, crimping and sealing preserve signal integrity and environmental protection.

⚠️ Common Signs of Failure

• Intermittent engine-control fault codes
• Broken conductors close to the ECU connector
• Corroded or pushed-back terminals
• Damaged connector seals
• Engine cuts out when the harness is moved
• High resistance or open circuit in a sensor or actuator wire

🛠️ Service Notes

• Compare the new harness with the old one before fitting — check the connector types, the number of pins and the branch lengths, and lay it out alongside the old loom to confirm every branch reaches its component
• Disconnect the batteries before unplugging or fitting a harness, and support the loom as you work so its weight never hangs on a connector or a bulkhead grommet
• Route it along the original path and secure it with the original clips and ties, clear of hot exhaust surfaces, sharp edges and anything that moves; leave a service loop at each connector rather than pulling a branch tight
• Push every connector home until the lock latches and protect the joints with a marine dielectric grease — an intermittent electrical fault is far more often a partly seated or salt-corroded pin than a broken wire
• Renewing the harness is the right repair where insulation is chafed, brittle or oil-soaked, or where corrosion has tracked inside the connector bodies; patch repairs in a damp engine bay tend to fail again, and any single conductor that is repaired should be joined with tinned marine cable of the same gauge, a proper crimp and adhesive-lined heat-shrink
