Mercury – CAN Data Harness (10-Pin, One Resistor) | 10-Foot SmartCraft Lead | 84-879980T10

Overview

Some SmartCraft networks need both extra length and proper termination built into the harness. The Mercury 84-879980T10 CAN Data Harness provides ten feet of SmartCraft cable with a single integrated resistor, making it useful for layouts where one end of the backbone needs a clean, built-in termination point. It carries CAN P, CAN X, and CAN H through the standard yellow 10-pin connector, keeping communication steady across a longer run.

Key Features

• 10-Foot Extension – Adds length for wider helm layouts or long rigging paths.
• One Integrated Resistor – Provides the required termination for networks needing a single end-point resistor.
• Yellow 10-Pin Connector – Standard SmartCraft plug carrying CAN P, CAN X, and CAN H.
• Full CAN Channel Support – Moves all SmartCraft data lines cleanly across the harness.
• Backbone Stability – Helps maintain proper electrical loading for SmartCraft communication.
• OEM Connector Quality – Factory ends ensure a tight, reliable fit in marine environments.

Compatibility

• SmartCraft CAN P networks
• SmartCraft CAN X networks
• SmartCraft CAN H networks
• Yellow 10-pin SmartCraft harness points requiring built-in termination

Performance & Practical Benefits

This harness gives you the extra length needed to cross larger consoles or complex rigging paths, while the integrated resistor helps stabilize the network where a termination point is required. It prevents signal issues that can come from missing or incorrect resistors and keeps communication smooth across modules and helm devices. Once installed, the system behaves predictably, even over longer runs.

Why Buy OEM

SmartCraft networks rely on precise resistor values and proper shielding. Mercury’s OEM harness guarantees the correct termination and clean data transfer, avoiding the noise and intermittent faults that cheaper cables can introduce. The connectors fit securely and hold up well in real-world marine vibration and exposure.

FAQ

Q1: When should I choose this harness with one resistor?
When the SmartCraft backbone requires a termination point and you also need a longer CAN run.

Q2: Does this replace a separate terminator plug?
Yes. The resistor is built into the harness, so no external terminator is needed at that end.

Q3: Will this affect SmartCraft readings?
No. It provides proper termination and clean data flow for reliable gauge and module behavior.

Q4: Is this suitable for DTS systems?
Yes, as long as the system uses the yellow 10-pin SmartCraft layout.

Q5: Is installation simple?
Yes. It plugs inline with factory connectors and routes like any standard SmartCraft cable.
