Mercury – CAN Data Harness (10-Pin, One Resistor) | 15-Foot SmartCraft Lead | 84-879980T15

Overview

Some SmartCraft setups need both a longer cable run and a built-in termination point, especially on bigger helms or when the network branches out across multiple modules. The Mercury 84-879980T15 CAN Data Harness provides fifteen feet of SmartCraft cable with one integrated resistor, giving the system the length it needs while also supplying the correct electrical load at that end of the backbone. It keeps CAN P, CAN X, and CAN H communication steady across a broader layout.

Key Features

• 15-Foot Extension – Gives you extra reach for long helm routes or wide rigging paths.
• Integrated Single Resistor – Provides proper termination at one end of the SmartCraft network.
• Yellow 10-Pin SmartCraft Plug – Standard connector carrying CAN P, CAN X, and CAN H.
• Full CAN Line Support – Moves all SmartCraft data channels cleanly through the harness.
• Network Stability – Helps prevent noise and dropouts caused by missing or incorrect termination.
• OEM Connector Build – Factory-fit ends ensure a tight, secure connection under vibration.

Compatibility

• SmartCraft CAN P networks
• SmartCraft CAN X networks
• SmartCraft CAN H networks
• Yellow 10-pin SmartCraft harness points requiring built-in termination

Performance & Practical Benefits

This harness gives your SmartCraft network both the distance and the termination it needs in one piece. The added length helps with clean routing on larger boats, while the integrated resistor stabilizes the backbone so gauges, modules, and helm devices communicate reliably. It removes the need for a separate terminator plug and keeps the rigging simpler and easier to follow.

Why Buy OEM

SmartCraft communication depends on exact resistor values, proper shielding, and tight-fitting connectors. Mercury’s OEM harness ensures the termination is correct and the signal stays clean across the longer run. Aftermarket cables often drift out of spec or introduce noise, but the factory harness delivers consistent, dependable performance over time.

FAQ

Q1: When is a 15-foot harness with a resistor needed?
When the SmartCraft backbone needs a termination point and the wiring has to span a longer distance.

Q2: Does this replace a separate terminator plug?
Yes. The resistor is built into the harness, so no additional terminator is required on that end.

Q3: Will this affect gauge or module behavior?
No. It simply provides proper termination and a longer CAN path.

Q4: Can it be used on DTS systems?
Yes—any system using the yellow 10-pin SmartCraft layout with termination handled at this end.

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