Mercury – CAN Data Harness (10-Pin, One Resistor, Non-DTS) | 50-Foot SmartCraft Lead | 84-879981T50

Overview

Large offshore boats, flybridge layouts, and long-distance rigging runs often need far more cable than the standard SmartCraft harness provides. The Mercury 84-879981T50 CAN Data Harness delivers fifty feet of non-DTS SmartCraft wiring with a single integrated resistor, giving the network both the reach it needs and the proper termination on one end. It keeps the wiring simple, stable, and long enough to span even the biggest layouts.

Key Features

• 50-Foot Extension – Maximum-length run for wide-beam boats, tall consoles, and multi-station setups.
• Integrated Single Resistor – Provides proper termination for one end of the CAN P backbone.
• Blue 10-Pin Connector – Built for non-DTS SmartCraft CAN P networks.
• Clean CAN P Path – Straight, no-branch harness for stable CAN communication.
• Backbone Stability – Helps prevent signal noise or dropouts caused by missing termination.
• OEM-Grade Construction – Factory connectors and shielding built for real-world marine environments.

Compatibility

• SmartCraft CAN P networks
• Non-DTS SmartCraft systems (blue connector)
• Installations requiring a long run with single end-of-line termination

Performance & Practical Benefits

This harness gives you the room to route SmartCraft wiring through long chase paths, up to flybridges, or across deep transoms without stretching the cable or forcing sharp bends. The integrated resistor provides the correct CAN P termination at one end, keeping communication clean and predictable. Once installed, the network behaves consistently, even across long distances and complex routing paths.

Why Buy OEM

SmartCraft systems depend heavily on accurate termination, pin alignment, and shielding—issues that cheap aftermarket cables often struggle with over long runs. Mercury’s OEM harness ensures the resistor value is correct and the connectors fit tightly, keeping the network stable season after season. The cable is built to endure vibration, moisture, and daily marine use.

FAQ

Q1: When is a 50-foot harness with one resistor necessary?
When a CAN P network needs maximum routing distance along with a built-in termination point.

Q2: Does this harness replace a separate terminator plug?
Yes. The resistor is built into the harness.

Q3: Will this change how SmartCraft modules function?
No. It simply provides correct termination and extends the communication line.

Q4: Can this be used on DTS networks?
No. It’s designed for non-DTS (blue connector) CAN P systems only.

Q5: Is installation straightforward?
Yes. It plugs inline with OEM connectors and routes like any other SmartCraft cable—just longer.
