Mercury – 5-Pin NMEA 2000 / CAN H Extension Harness | 0.5 m | 84-879171T01

Overview
The 84-879171T01 Extension Harness adds a short 0.5-meter reach to your NMEA 2000 or Mercury CAN H network—ideal for tight helm spaces where your IMU or GPS module needs just a little extra slack. It keeps the rigging clean without adding unnecessary cable length.

Key Features

• 0.5-Meter Extension – Short, precise length for compact routing paths.
• Male-to-Female 5-Pin – Standard Micro-C connectors for NMEA 2000 and CAN H.
• Ideal for IMU/GPS – Maintains clean signal transfer for network sensors.
• Marine-Durable – Flexible cable jacket built for vibration and moisture.
• Plug-In Fit – No splicing; connects directly to existing backbone.

Compatibility

• NMEA 2000 networks (Micro-C 5-pin)
• Mercury CAN H bus
• IMU, GPS, and heading sensors

Performance & Practical Benefits
This short harness is perfect when your module sits just out of reach of the backbone. It prevents tension on connectors and allows cleaner cable routing behind the dash. Signal integrity remains strong thanks to proper pin alignment and Mercury’s OEM waterproofing.

Why Buy OEM
OEM connectors lock securely, stay sealed, and maintain full N2K/CAN H signal quality. Generic extensions often loosen under vibration or corrode, creating intermittent dropouts that are hard to diagnose. Mercury’s harness delivers long-term reliability.
