Mercury – CAN Data Harness (10-Pin, No Resistors) | 15-Foot SmartCraft Lead | 84-879969T15

Overview

Long SmartCraft runs need a clean, uninterrupted cable to keep communication steady, especially on larger consoles or boats with long rigging paths. The Mercury 84-879969T15 CAN Data Harness adds fifteen feet of non-terminated SmartCraft wiring, giving you the space to route the harness properly without straining the original cable. It carries CAN P, CAN X, and CAN H signals through the standard yellow 10-pin connector, making it a solid choice for systems that already have termination handled elsewhere.

Key Features

• 15-Foot Extension – Provides extra reach for long SmartCraft routing paths on bigger boats.
• 10-Pin Yellow Connector – Standard SmartCraft plug carrying CAN P, CAN X, and CAN H.
• Non-Terminated Harness – For systems with network resistors already installed.
• Full CAN Signal Support – Passes all SmartCraft communication channels cleanly.
• For Multi-Bus Systems – Built for SmartCraft layouts using CAN P, X, and H.
• OEM Connector Quality – Factory ends ensure a tight, secure fit that holds up underway.

Compatibility

• SmartCraft CAN P networks
• SmartCraft CAN X networks
• SmartCraft CAN H networks
• Standard yellow 10-pin SmartCraft harness points

Performance & Practical Benefits

The added length makes routing easier across wider helms and deeper console layouts. You can run the harness through cleaner, more natural paths without forcing bends or stretching the cable. Once installed, CAN communication stays steady, helping SmartCraft modules and helm devices respond reliably even over long distances.

Why Buy OEM

SmartCraft systems depend on clean electrical paths and correctly pinned connectors. Mercury’s OEM harness preserves signal quality and shielding, avoiding the glitches or dropouts that cheaper cables often introduce—especially on longer runs. The factory build holds up through vibration, humidity, and everyday marine use.

FAQ

Q1: When should I use a 15-foot SmartCraft CAN harness?
When modules are spaced far apart and the standard harness is too short for a clean routing path.

Q2: Does this harness include resistors?
No. It’s a non-terminated harness for systems where CAN termination is already located elsewhere.

Q3: Will this affect how SmartCraft modules behave?
No. It simply extends the CAN P, X, and H communication lines.

Q4: Can this be used on DTS setups?
Yes, as long as the system uses the standard 10-pin SmartCraft layout and proper termination is already installed.

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