Mercury – CAN Data Harness (10-Pin, One Resistor, Non-DTS) | 25-Foot SmartCraft Lead | 84-879981T25

Overview

Some SmartCraft CAN P networks need both a long routing run and proper termination built directly into the harness. The Mercury 84-879981T25 CAN Data Harness delivers twenty-five feet of blue-connector SmartCraft cable with a single integrated resistor, giving the network the correct load on one end while providing the reach needed for wider helms, deep consoles, or long rigging corridors. It keeps the wiring cleaner and the system communication steady.

Key Features

• 25-Foot Extension – Offers extended reach for larger boats and long rigging paths.
• Integrated Single Resistor – Provides one end of the CAN P backbone with proper termination.
• Blue 10-Pin Connector – Built for non-DTS SmartCraft CAN P networks.
• Straight CAN P Path – Carries SmartCraft data consistently without extra branches.
• Backbone Stability – Helps eliminate data dropouts caused by insufficient termination.
• OEM Quality Build – Factory shielding and connectors designed for real-world marine use.

Compatibility

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

Performance & Practical Benefits

This harness gives your SmartCraft network both the reach and the stability it needs. The additional length helps route the CAN line smoothly through longer console spaces or structural paths without stressing the cable. With one resistor built in, the harness also closes that end of the backbone cleanly, preventing CAN noise or intermittent faults. Once installed, SmartCraft communication remains steady and predictable.

Why Buy OEM

Termination accuracy and proper shielding are critical in SmartCraft networks. Mercury’s OEM harness ensures the correct resistor value, secure connector fit, and stable CAN signal flow. Cheaper cables often introduce noise or poor termination that leads to frustrating communication problems. The factory harness stays reliable even with vibration, moisture, and daily marine use.

FAQ

Q1: When is a 25-foot harness with one resistor the right fit?
When the network needs a long routing path and a termination point built into the same harness.

Q2: Does this replace a separate terminator plug?
Yes. The built-in resistor provides the needed termination on that end.

Q3: Does it change SmartCraft module behavior?
No. It stabilizes the network but doesn’t alter module function.

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

Q5: Is installation simple?
Yes. It plugs into the existing SmartCraft connectors and routes like any standard harness.
