## ⚙️ Key Features

-   EVC bus and steering adapter cable
-   Approximate length: 0.17 m / 0.6 ft
-   Factory marine connectors
-   Used in main-station and docking-station installations
-   Carries control-network signals

## 🔌 Function

The cable provides a short network connection between EVC, steering and engine-control components.

## ⚠️ Common Signs of Failure

-   EVC communication fault
-   Docking or steering station unavailable
-   Intermittent network operation
-   Water or corrosion at connectors
-   Damaged cable or locking tabs

## 🛠️ Service Notes

-   Isolate the battery before disconnecting or reconnecting anything, and make sure connectors are clean, dry and fully latched before switching the system back on
-   Route the new cable along the original path and secure it with the original clips, ties and stand-offs; unsupported cable chafes through wherever it touches a bracket, hose or edge
-   Keep the run clear of the exhaust and turbocharger, away from moving parts and sharp edges, and use a grommet or gland wherever it passes through a panel or bulkhead
-   Protect the connections against damp — a properly seated and sealed connector survives an engine bilge atmosphere far better than a taped joint
-   Replace a damaged cable rather than patching it; where a repair is unavoidable use a crimped and sealed joint, never solder as the only mechanical connection
