Mercury – CAN Data Harness (10-Pin, No Resistors, Non-DTS) | 30-Foot SmartCraft Lead | 84-879968T30

Overview

Large helms, flybridge layouts, and deep rigging channels often need a long, clean SmartCraft extension to keep the data line routed naturally. The Mercury 84-879968T30 CAN Data Harness gives you thirty feet of non-terminated SmartCraft cable using the blue 10-pin connector, built specifically for CAN P networks that do not use DTS. With no added branches or extra circuits, it provides a simple, reliable way to extend the data path across long distances without stressing the original harness.

Key Features

• 30-Foot Extension – Ideal for long helm runs, tall consoles, and wide-beam rigs.
• Blue Non-DTS Connector – Standard SmartCraft plug made for CAN P networks only.
• No Internal Resistors – Designed for systems where CAN termination is handled elsewhere.
• Straight CAN P Path – Pure SmartCraft communication without added leads or breakout circuits.
• Clean Routing Flexibility – Helps avoid tight bends and overextended cable runs.
• OEM Marine Build – Factory-grade connectors and shielding handle vibration and moisture.

Compatibility

• SmartCraft CAN P networks
• Non-DTS SmartCraft systems (blue 10-pin)
• Standard SmartCraft helm and rigging connection points

Performance & Practical Benefits

This harness is built for boats that need maximum routing distance without complicating the network. The thirty-foot length allows the cable to run through bulkheads, under decks, or along long console spans while staying relaxed and easy to manage. Because it has no resistors or add-on circuits, it keeps the network simple and dependable—just a clean CAN P link that communicates steadily from end to end.

Why Buy OEM

SmartCraft communication depends on correct pin alignment, secure connectors, and proper shielding. Mercury’s OEM harness maintains those standards, preventing the signal noise, dropouts, or loose-fit issues common with cheaper cables—especially over long distances. The factory build ensures the harness holds up in real marine conditions.

FAQ

Q1: When is the 30-foot non-DTS harness the right choice?
When a CAN P network needs maximum routing distance across a large helm or long rigging chase.

Q2: Does this harness include termination resistors?
No. It’s a non-terminated harness for systems that already have termination installed elsewhere.

Q3: Will this affect SmartCraft module behavior?
No. It simply extends the CAN P communication line.

Q4: Can this be used on DTS systems?
No. This blue connector version is designed only for non-DTS CAN P layouts.

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