Mercury – CAN Data Harness (10-Pin, Two Resistors, Non-DTS) | 20-Foot SmartCraft Lead | 84-8M0210758

Overview

Some SmartCraft networks need a fully terminated backbone in a single harness—especially on smaller boats or non-DTS layouts where the network is simpler but still needs proper load and clean signal paths. The Mercury 84-8M0210758 CAN Data Harness provides twenty feet of SmartCraft cable with two integrated termination resistors, along with dedicated horn and link-gauge connections. It’s a clean, all-in-one solution for building or extending a CAN P network without adding extra plugs or components.

Key Features

• 20-Foot Extension – Long reach for helms, consoles, and bulkhead-to-rigging runs.
• Dual Resistors Built In – Contains both termination resistors needed to finish a CAN P backbone.
• Blue 10-Pin SmartCraft Plug – Non-DTS connector designed for CAN P systems.
• Horn & Link Gauge Leads – Includes built-in connections for horn and Link Gauge integration.
• CAN P Data Path – Carries SmartCraft CAN P communication cleanly through the harness.
• OEM Construction – Factory connectors and shielding hold up in real marine conditions.

Compatibility

• SmartCraft CAN P networks
• Non-DTS SmartCraft systems (blue connector)
• SmartCraft horns and Link Gauges
• Helm and rigging layouts needing a fully terminated CAN backbone

Performance & Practical Benefits

This harness creates a complete, terminated CAN P network right out of the box. With both resistors built in, there’s no need to add terminator plugs or track down separate components—the network gets the correct load automatically. The extra length makes routing easier through long console spaces or wide rigs, and the added horn and Link Gauge connections help consolidate wiring into one tidy harness. Once installed, communication stays steady and predictable.

Why Buy OEM

SmartCraft data is sensitive to termination quality and pin accuracy. Mercury’s OEM harness ensures the resistor values, connector fit, and shielding meet the system’s exact electrical expectations. Aftermarket cables often mismatch the termination or create noisy signals, but the factory harness delivers stable communication over long distances and holds up well under vibration and moisture.

FAQ

Q1: When is this dual-resistor harness the right choice?
When building or extending a non-DTS CAN P network that requires both backbone termination points in a single harness.

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

Q3: What’s the benefit of the horn and Link Gauge leads?
They simplify rigging by giving those functions a clean, direct connection inside the same harness.

Q4: Can I use this on DTS systems?
No. This is a non-DTS (blue connector) harness designed only for CAN P networks.

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