24778499 Wiring Harness | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta wiring harness, part number 24778499, from the Cables and Fuses group. A harness is a made-up loom rather than a length of cable: the conductors are cut to length, terminated in keyed connectors and bound into one routed assembly, which is why a harness only fits the run it was built for and cannot be adapted to another. Volvo Penta's own parts listing carries the name alone: no rating, no dimension and no engine application are published against this number. Six harnesses are listed here (24713515, 24768428, 24768838, 24836213, 24853454) sharing that same name and group, and nothing published separates them, so order by the number quoted on the parts list or wiring drawing for your own installation.

⚙️ Key Features

• Wiring harness, from the cables and fuses group
• No length, conductor count or connector type is published against this number
• Six harnesses listed here share this name; nothing published tells them apart
• Order by part number against the parts list for your wiring for your installation

🔌 Function

Carries power and signals between the units it links, holding every conductor in one routed, supported loom that ends in connectors which will only mate one way.

⚠️ Common Signs of Failure

• Intermittent faults or warnings that come and go with vibration or with wet weather
• A circuit dead altogether while both units at either end test good
• Green or white corrosion on the connector pins, or pins pushed back in the housing
• Insulation chafed, cracked or melted where the loom passes a bracket, edge or hot surface
• Water tracking into a connector whose seal or blanking cap has been lost

🛠️ Service Notes

• Volvo Penta's EVC installation instructions are explicit that its harnesses must never be cut or modified, and that extra power for an accessory is taken through the proper relay instead of by splicing into the loom
• The same instructions require cables to enter a control unit so that water cannot run down them into the unit or into the loom, so keep the original drip loops and seals
• Refit the protective caps on any unused connectors and support the loom on its original clips, clear of hot surfaces and sharp edges

📦 Condition
