# 21260206 Wiring Harness | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine engine wiring harness used in a Volvo Penta cables-and-fuses installation. It provides the factory conductor sizes, branch lengths, terminal population and connector sealing required by the assigned engine-control and electrical configuration.

## 🚤 Compatibility

-   **Engine Family:** D, IPS
-   **HP Range:** 260-435 HP

Full model list at the end of this description.

## ⚙️ Key Features

-   Genuine Volvo Penta engine harness
-   Factory-moulded connectors and branch routing
-   Marine- and industrial-grade insulation
-   Carries power, sensor, actuator and control circuits
-   Exact engine and option configuration controls fitment
-   Quantity varies by assembly, most commonly one

## 🔌 Function

The harness distributes electrical power and carries sensor, actuator and control signals between the engine components and control system.

## ⚠️ Common Signs of Failure

-   Intermittent starting or running faults
-   Several unrelated circuit fault codes
-   Open- or short-circuit readings
-   Corroded or pushed-back connector terminals
-   Heat, oil or abrasion damage
-   Fault changes 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
