Mercury – CAN Data Harness (10-Pin, One Resistor, Non-DTS) | 15-Foot SmartCraft Lead | 84-879981T15

Overview

Some SmartCraft CAN P networks need a longer run and a built-in termination point to stay stable. The Mercury 84-879981T15 CAN Data Harness handles both at once. With fifteen feet of blue-connector SmartCraft cable and a single integrated resistor, it gives the network the correct load on one end while providing enough length to route through wider helms or longer rigging paths. It keeps the wiring simple and the communication steady.

Key Features

• 15-Foot Extension – Offers extra reach for larger helm layouts and extended routing paths.
• Integrated Single Resistor – Supplies the proper termination for one end of a CAN P backbone.
• Blue 10-Pin Connector – Designed specifically for non-DTS SmartCraft CAN P systems.
• Clean CAN P Path – Carries SmartCraft communication without added branches or circuits.
• Backbone Stability – Helps prevent signal issues caused by missing or incorrect termination.
• OEM Build Quality – Factory connectors and shielding withstand vibration and marine exposure.

Compatibility

• SmartCraft CAN P networks
• Non-DTS SmartCraft systems (blue connector)
• Installations requiring a built-in single terminator

Performance & Practical Benefits

This harness gives your SmartCraft network the length it needs while also closing one end of the backbone with the correct resistor value. It keeps the wiring relaxed, makes routing easier around bulkheads or deeper consoles, and eliminates the need for a separate terminator plug. Once connected, the CAN P signal stays steady so modules and gauges communicate reliably.

Why Buy OEM

SmartCraft systems are sensitive to termination accuracy and connector quality. Mercury’s OEM harness uses the correct resistor spec and proper shielding to keep the data clean. Aftermarket options often introduce electrical noise or loose-fit issues, especially over longer distances. The factory harness stays reliable through vibration, humidity, and everyday marine use.

FAQ

Q1: When is this 15-foot harness with one resistor useful?
When a CAN P network needs both extra routing distance and a built-in termination point on one end.

Q2: Does this replace a standalone terminator?
Yes. The resistor is integrated directly into the harness.

Q3: Will this change module or gauge behavior?
No. It simply ensures proper termination and extends the CAN P line.

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

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