Description

84-899888T22 VESSEL SENSOR EXTENSION HARNESS
Vessel sensor extension harness (Optional) 10 feet
All Diesel products Non DTS and DTS including Axius

*This is a genuine Mercury Marine part.

Harness Assembly is a critical integrated component of marine electrical systems, enabling systematic power distribution and signal transmission between engines, control units, and instrumentation. By combining cables, connectors, and protective sleeves with precision, it ensures electrical connectivity reliability, noise immunity, and maintenance convenience. Its modular design resists erosion from vibration, moisture, and temperature fluctuations, significantly enhancing operational stability and safety.
This product range includes engine harnesses, console harnesses, and sensor-specific harnesses, developed for different vessel electrical architectures and electromagnetic requirements. Each harness utilizes marine-grade flame-retardant wires, gold-plated contacts, and waterproof interfaces, with shielding and insulation strictly adhering to Mercury Marine standards. Selection based on equipment layout, current load, and signal type is essential for system compatibility and long-term stability.
Harness assemblies employ high-precision mold-crimped terminals and UV-resistant woven sleeves to maintain electrical performance in harsh environments such as salt spray and oil exposure. Color-coded management and numbering systems facilitate quick troubleshooting, while branched protection structures effectively prevent cable abrasion.
Regular inspection of connection integrity and insulation resistance helps prevent potential faults like short circuits or signal degradation. Whether used in new vessel construction, system upgrades, or maintenance replacements, this product provides highly integrated and reliable solutions for marine electrical systems.
