Mercury – CAN Data Harness (10-Pin, Dual Resistors, Non-DTS) | 30-Foot SmartCraft Lead | 84-879982T30

Overview

Large boats and long rigging paths often need a SmartCraft harness that can handle both distance and termination without extra parts. The Mercury 84-879982T30 CAN Data Harness does exactly that. With thirty feet of reach and two built-in termination resistors, it forms a complete CAN P backbone in a single run. It also includes dedicated leads for the horn and Link Gauge, keeping the wiring tidy and reducing the need for extra adapters behind larger helms.

Key Features

• 30-Foot Extension – Long reach for oversized consoles, flybridge layouts, or deep rigging channels.
• Integrated Dual Resistors – Provides both termination points needed for a full CAN P network.
• Blue 10-Pin Connector – Non-DTS SmartCraft connection designed for CAN P systems.
• Horn & Link Gauge Leads – Built-in tie-in points for these functions to simplify wiring.
• Full CAN P Signal Support – Carries SmartCraft CAN P communication cleanly from end to end.
• OEM Construction – Factory connectors and shielding ensure a durable, marine-grade connection.

Compatibility

• SmartCraft CAN P networks
• Non-DTS SmartCraft systems (blue connector)
• SmartCraft horn circuits
• SmartCraft Link Gauge setups
• Installations requiring built-in CAN P termination

Performance & Practical Benefits

This harness gives you a clean, fully terminated CAN P backbone that can stretch across large helm spaces or complex routing paths. With both resistors already inside the harness, the network gets the correct electrical load without tracking down separate terminators. The added horn and Link Gauge leads help keep the rigging organized and reduce clutter behind the dash. Once installed, CAN P communication stays steady, even over long distances.

Why Buy OEM

SmartCraft systems are sensitive to poor termination and off-spec wiring. Mercury’s OEM harness guarantees the correct resistor values, proper shielding, and dependable connector fit that the network expects. Cheaper cables often create intermittent data problems over long runs, but the factory harness stays solid under vibration, heat, and everyday marine conditions.

FAQ

Q1: When should I use this 30-foot harness with dual resistors?
When the SmartCraft CAN P network needs both long reach and complete termination built right into one harness.

Q2: Does this eliminate the need for separate terminators?
Yes. Both resistors are already built into the harness.

Q3: Why are the horn and Link Gauge leads included?
They allow those components to connect directly without extra adapters or splitters.

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

Q5: Is installation easy?
Yes. It plugs in with OEM connectors and routes like any standard SmartCraft cable.
