Mercury – Diesel Vessel Sensor Harness | Inboard Sensor Wiring Harness | 84-899887T08

The Mercury Diesel Vessel Sensor Harness is designed for diesel inboard applications where optional vessel sensors must communicate reliably with the engine system. It provides a centralized, protected connection point that keeps sensor wiring organized while maintaining clean, stable signal transmission throughout the electrical network.

This harness supports both DTS and non-DTS diesel inboard setups (excluding TDI engines). It is used when additional sensor data is required beyond the base engine configuration, allowing expanded monitoring capability without introducing electrical noise or compromising overall system reliability.

Key Features

• Diesel Inboard Vessel Sensor Harness – Designed specifically for optional sensor integration
• Expanded Sensor Capability – Supports additional vessel sensors beyond base engine wiring
• DTS & Non-DTS Compatible – Works with Mercury diesel inboard control systems
• Marine-Grade Construction – Built to withstand vibration, moisture, and engine-room heat
• OEM Mercury Connectors – Ensure secure fit and factory-correct electrical connections

Engine & Boat Compatibility

• Mercury diesel engines
• Diesel inboard systems
• DTS inboard control systems
• Non-DTS inboard control systems
• Tier 2 diesel series
• Tier 3 diesel series
• Not compatible with TDI engines

Important Notes

• Designed specifically for diesel inboard sensor integration.
• Used only when additional vessel sensors are being added.
• Not a replacement for the primary engine wiring harness.
• Excludes TDI diesel applications.

FAQs

1) What is this vessel sensor harness used for?
It provides a dedicated connection point for optional vessel sensors on diesel inboard systems, allowing clean and reliable signal communication.

2) Does this harness support DTS systems?
Yes. It supports both DTS and non-DTS diesel inboard control systems.

3) Is this required on all diesel inboard engines?
No. It is only needed when adding vessel sensors beyond the base engine configuration.

4) Can this be used on diesel sterndrive setups?
No. This harness is designed specifically for diesel inboard applications. A different harness is required for sterndrive systems.

5) Why should OEM wiring be used for sensor integration?
OEM harnesses use proper shielding, wire length, and connector fitment to prevent signal interference, communication faults, and long-term reliability issues.
