# 23774267 Wiring Harness | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta wiring harness 23774267, listed in the Marine Propulsion group rather than with the other two harnesses here, which sit under Cables and Fuses. On Volvo Penta's electronic control systems the harnesses are the spine of the installation. The engine and transmission harness runs from the powertrain unit to the engine, the gearbox and the tank and rudder senders, with the sender legs colour-coded so they cannot be crossed, and it carries the diagnostic connector the dealer tool plugs into. Bus cables, Y-connectors and extension cables then join the units to each other. No length, connector count, pin-out or engine application is published for this number. If you are choosing between it and 23472419 or 23838376, the system group is the only distinction on record, and it is not enough on its own, so match the number against the loom you are replacing.

## 🛠️ Service Notes

-   Volvo Penta's EVC installation manual is blunt about this: never cut or modify a Volvo Penta harness, and use the accessory relay if extra power is needed
