Mercury – CAN Data Harness (10-Pin, No Resistors) | 4-Foot DTS Lead | 84-879312T47

Overview

Some DTS setups need a bit more reach than the short factory leads allow, especially when modules sit on opposite sides of the helm or deeper in the console. The Mercury 84-879312T47 CAN Data Harness adds four feet of non-terminated SmartCraft length, giving you a clean, stable connection for CAN 1, CAN 2, and CAN 3 without altering the network’s existing termination. It’s a simple way to get better routing flexibility while keeping the DTS system steady and predictable.

Key Features

• 4-Foot CAN Extension – Adds moderate length for smoother DTS rigging and cleaner routing.
• 10-Pin Yellow DTS Connector – Standard SmartCraft DTS plug carrying all active CAN lines.
• No Termination Built In – For systems where resistors are already located elsewhere in the network.
• Supports All CAN Channels – Passes CAN 1, CAN 2, and CAN 3 communication without interruption.
• DTS-Specific Design – Intended for Digital Throttle & Shift SmartCraft applications.
• OEM Connector Quality – Factory-fit ends help ensure a tight, reliable connection.

Compatibility

• SmartCraft DTS systems
• CAN 1 / CAN 2 / CAN 3 network paths
• Yellow 10-pin DTS harness points
• SmartCraft CAN Bus modules

Performance & Practical Benefits

This harness adds just enough length to make routing easier in crowded or oddly shaped helm areas. With four extra feet, the cable can be run around bulkheads or behind wider panels without straining the original harness. Because it’s non-terminated, it won’t interfere with the system’s existing resistor layout. Once connected, DTS modules continue to communicate cleanly and consistently.

Why Buy OEM

DTS relies on accurate CAN signaling, and Mercury’s OEM harness preserves that integrity. The connectors lock firmly, the shielding is built for marine use, and the pin alignment stays true—helping avoid the intermittent behavior that can show up with aftermarket cables. It’s a dependable link designed for long-term reliability.

FAQ

Q1: When should I choose the 4-foot DTS CAN harness?
When modules sit too far apart for a shorter cable but don’t require the long reach of a larger extension.

Q2: Does this harness contain resistors?
No. It’s a non-terminated harness meant for DTS systems with termination already in place.

Q3: Does it affect engine shifting or throttle feel?
No. It only carries CAN data between DTS components.

Q4: Can it be used outside DTS networks?
It’s intended specifically for 10-pin yellow DTS SmartCraft connections.

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