Mercury – CAN Data Harness (10-Pin, No Resistors) | 10-Foot SmartCraft Lead | 84-879969T10

Overview

Longer SmartCraft runs sometimes need a clean stretch of cable without extra components in the way. The Mercury 84-879969T10 CAN Data Harness gives you ten feet of non-terminated SmartCraft wiring, carrying CAN P, CAN X, and CAN H signals through the standard yellow 10-pin connector. It’s made for systems that already have proper termination elsewhere and just need a solid, OEM-quality link with more reach.

Key Features

• 10-Foot Extension – Adds substantial length for wider helms and long routing paths.
• 10-Pin Yellow SmartCraft Plug – Standard connector carrying CAN P, CAN X, and CAN H.
• No Built-In Resistors – Works in networks where termination is already handled.
• Full CAN Channel Support – Passes all SmartCraft communication lines cleanly.
• SmartCraft System Ready – Designed for systems using CAN P, X, and H architecture.
• OEM Connector Fit – Factory ends ensure a reliable, vibration-resistant connection.

Compatibility

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

Performance & Practical Benefits

This harness gives you the freedom to route SmartCraft wiring through larger consoles, behind bulkheads, or along longer helm paths without forcing tight bends or stretching the cable. The signal moves cleanly across the added distance, keeping communication between SmartCraft modules steady. It’s a practical fix for boats that need more room to run the data backbone the right way.

Why Buy OEM

SmartCraft networks depend on proper pin alignment, clean shielding, and durable connectors. Mercury’s OEM harness maintains all three, preventing the noise or intermittent faults that cheaper cables often introduce. It stays secure under vibration and handles the everyday wear of marine use without losing signal quality.

FAQ

Q1: When should I choose the 10-foot extension?
When SmartCraft modules are spaced far apart and the original harness won’t reach cleanly.

Q2: Does this harness include resistors?
No. It must be used in systems where termination is already in place.

Q3: Does it affect module behavior?
No. It simply extends CAN P, X, and H communication lines.

Q4: Can it be used on DTS systems?
Yes, as long as the system uses the standard 10-pin SmartCraft layout and proper termination is established elsewhere.

Q5: Is installation straightforward?
Yes. It plugs inline and routes like any standard SmartCraft cable.
