Mercury – CAN Data Harness (10-Pin, No Resistors, Non-DTS) | 20-Foot SmartCraft Lead | 84-879968T20

Overview

Longer helm layouts and deep rigging channels sometimes need more reach than the standard SmartCraft lead can offer. The Mercury 84-879968T20 CAN Data Harness gives you twenty feet of clean, non-terminated SmartCraft cable using the blue 10-pin connector—built specifically for CAN P networks that don’t use DTS. With no extra branches or circuits, it’s a simple extension that helps the data line travel farther without stressing the original harness.

Key Features

• 20-Foot Extension – Adds ample length for wide helms, tall consoles, or long routing paths.
• Blue Non-DTS Connector – Standard SmartCraft plug designed for CAN P networks.
• No Built-In Resistors – For systems where termination is already handled elsewhere.
• Straight Data Path – Pure CAN P communication with no added leads or circuits.
• Clean Routing Flexibility – Helps avoid tight bends and cable tension in long runs.
• OEM Construction – Factory-grade connectors and shielding for dependable marine use.

Compatibility

• SmartCraft CAN P networks
• Non-DTS SmartCraft systems (blue 10-pin)
• Standard SmartCraft helm and rigging connection points

Performance & Practical Benefits

This harness gives you the freedom to route SmartCraft wiring across wider consoles or deeper rigging corridors without overextending the cable. The extra length helps the harness sit naturally, reduces strain on connectors, and keeps the backbone cleaner and easier to follow. With no built-in resistors or branches, the network stays simple and steady—just a clean CAN P extension that does its job quietly.

Why Buy OEM

SmartCraft communication depends on tight-fit connectors, correct pin alignment, and proper shielding. Mercury’s OEM harness keeps the data smooth and stable, avoiding the dropouts or electrical noise that cheaper cables can introduce—especially over longer distances. It’s built for vibration, moisture, and the daily movement of a working boat.

FAQ

Q1: When is a 20-foot non-DTS SmartCraft harness useful?
When a CAN P network needs extra length to reach across a large helm or through a long rigging route.

Q2: Does this harness include resistors?
No. It’s meant for systems with termination already in place.

Q3: Will this affect gauge or module behavior?
No. It simply extends the CAN P communication line.

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

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