Mercury – Vessel Sensor Extension Harness 15 Foot | Sensor Extension Harness | 84-899888T23

The Mercury Vessel Sensor Extension Harness (15 Foot) is designed for Mercury diesel installations where sensor wiring must travel longer distances between vessel sensors, interface modules, and control components. It is commonly used on larger boats where standard sensor leads are not long enough to route cleanly through engine rooms or rigging passages.

The 15-foot length allows relaxed, strain-free routing without splices, tight bends, or connector stress. By preserving factory shielding and connector integrity, this extension harness helps maintain stable sensor communication while keeping diesel monitoring systems organized and reliable over extended runs.

Key Features

• Diesel Vessel Sensor Extension – Extends existing Mercury diesel sensor wiring
• 15-Foot Length – Designed for longer routing paths in larger installations
• OEM Mercury Connectors – Maintain proper signal integrity and secure factory fit
• Factory-Compatible Shielding – Supports clean, interference-free data transmission
• Marine-Grade Construction – Built to withstand vibration, moisture, and engine-room conditions

Engine & Boat Compatibility

• Mercury diesel engines
• DTS diesel control systems
• Axius diesel systems
• Mercury diesel electronic monitoring networks

Important Notes

• Used only to extend an existing vessel sensor harness.
• Does not replace the primary vessel sensor harness.
• Eliminates the need for splicing or custom wiring.
• Ensure proper routing to avoid sharp bends, pinch points, or connector strain.

FAQs

1) When should I use the 15-foot extension harness?
Use this harness when sensor wiring must travel long distances across large engine rooms, bulkheads, or rigging tunnels.

2) Is this compatible with DTS and Axius diesel systems?
Yes. It is compatible with Mercury DTS and Axius diesel configurations.

3) Can this be used on gasoline engines?
No. This harness is designed specifically for Mercury diesel sensor systems.

4) Why not use generic wiring extensions?
Non-OEM extensions can introduce electrical noise, poor connector fit, and signal dropouts. OEM harnesses preserve proper shielding and data integrity.

5) Where is this harness typically installed?
Common locations include engine rooms, rigging passages, bulkhead transitions, and near vessel interface or sensor modules.
