22029558 Wiring Harness | Genuine Volvo Penta Part

🔧 Product Description

Factory extension harness used in a Volvo Penta diesel-engine electrical installation. It extends the original circuit with the correct connectors, conductor size and branch length without altering the approved wiring arrangement.

🚤 Compatibility

Typically suits:

• Volvo Penta V8-350-CE-H
• Volvo Penta V8-300-CE-G
• Volvo Penta V8-300-CE-H
• Volvo Penta V8-350-CE-G

• Engine Family: V
• HP Range: 300-350 HP

⚙️ Key Features

• Factory connector and pin configuration
• Extension-harness construction
• Marine/industrial electrical-system protection
• Maintains circuit routing and service access
• Must be matched by connector layout and serial number
• Engine type: Electronically controlled Volvo Penta diesel engine

🔌 Function

Extends the assigned electrical circuit between engine, control or installation components while maintaining the original voltage, signal and grounding paths.

⚠️ Common Signs of Failure

• Intermittent open-circuit or communication faults
• High resistance or voltage drop through the extension
• Chafed insulation or moisture entry
• Faults that appear when the harness is moved

🛠️ 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
