Mercury – CAN Data Harness (10-Pin, Dual Resistors, Non-DTS) | 25-Foot SmartCraft Lead | 84-879982T25

Overview

When a SmartCraft CAN P network needs both extra length and built-in termination, this harness covers everything in one clean piece. The Mercury 84-879982T25 CAN Data Harness provides twenty-five feet of blue-connector SmartCraft cable with two integrated resistors, giving the network the proper end-to-end load without separate terminator plugs. It also includes connections for the horn and Link Gauge, keeping the rigging simple and organized on larger helm layouts.

Key Features

• 25-Foot Extension – Long run for wide helms, tall consoles, or deep rigging channels.
• Integrated Dual Resistors – Provides both termination points required for a complete CAN P backbone.
• Blue Non-DTS Connector – Built for CAN P systems that don’t use the DTS yellow connector.
• Horn & Link Gauge Leads – Offers dedicated connection points for these functions in one harness.
• Full CAN P Signal Support – Carries SmartCraft CAN P communication cleanly and consistently.
• OEM Marine Quality – Factory connectors and shielding keep the network stable in real-world conditions.

Compatibility

• SmartCraft CAN P networks
• Non-DTS SmartCraft systems (blue 10-pin connector)
• SmartCraft horn circuits
• SmartCraft Link Gauges
• Installations requiring built-in CAN backbone termination

Performance & Practical Benefits

This harness gives your CAN P system the length it needs while also handling termination internally, making installation easier and cleaner. The tab-ready leads simplify connecting the horn or Link Gauge, reducing the number of extra adapters behind the helm. With both resistors built in, the network gets the correct load automatically, helping eliminate nuisance communication drops and keeping data steady across long runs.

Why Buy OEM

SmartCraft communication depends on correct resistor values, tight connectors, and proper shielding. Mercury’s OEM harness delivers exactly that, ensuring each module receives clean, uninterrupted CAN P signals. Aftermarket versions often miss the electrical spec or fit loosely, which can lead to unpredictable network behavior. The factory harness stays reliable in vibration, humidity, and daily marine use.

FAQ

Q1: When should I use this 25-foot harness with dual resistors?
When the SmartCraft CAN P network needs both length and full backbone termination built into one harness.

Q2: Does this replace separate terminator plugs?
Yes. Both required resistors are already integrated.

Q3: What’s the purpose of the horn and Link Gauge leads?
They give those components a simple, direct tie-in without extra splitters or adapters.

Q4: Can this harness be used on DTS systems?
No. It’s intended for non-DTS (blue connector) CAN P layouts only.

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