Mercury – CAN Data Harness (10-Pin, No Resistors) | 3-Foot DTS Lead | 84-879312T46

Overview

Some DTS installations need a little more distance between modules to keep the wiring relaxed and properly routed. The Mercury 84-879312T46 CAN Data Harness adds three feet of non-terminated SmartCraft length, carrying CAN 1, CAN 2, and CAN 3 signals through the standard yellow 10-pin DTS connector. It’s built for systems that already have the correct termination in place and just need a clean, stable CAN link with extra reach.

Key Features

• 3-Foot CAN Extension – Offers added length for DTS rigs with wider or more complex routing.
• 10-Pin Yellow DTS Connector – Uses Mercury’s standard DTS plug with all CAN channels active.
• No Internal Resistors – Designed for networks where CAN termination exists elsewhere.
• Full CAN Signal Support – Transmits CAN 1, CAN 2, and CAN 3 communication lines reliably.
• Purpose-Built for DTS – Intended for Digital Throttle & Shift SmartCraft systems.
• OEM Connector Quality – Factory-fit SmartCraft ends ensure a tight, dependable snap-in connection.

Compatibility

• SmartCraft DTS systems
• CAN 1 / CAN 2 / CAN 3 network branches
• Yellow 10-pin DTS harness connections
• SmartCraft CAN Bus modules and devices

Performance & Practical Benefits

This harness gives DTS setups more room to breathe, helping avoid tight bends and stressed connectors when modules are spaced farther apart. The longer run makes routing cleaner behind large helms or along deeper console paths. Since it’s a non-terminated harness, it doesn’t interfere with the system’s existing resistor layout. Once installed, DTS communication stays smooth and predictable.

Why Buy OEM

DTS communication relies on clean CAN signaling, and Mercury’s OEM harness maintains the shielding, pin alignment, and connector quality required for stable operation. Cheaper extensions often introduce noise or poor fitment, creating intermittent DTS behavior that’s tough to diagnose. The OEM harness keeps the network steady over time and handles vibration and marine exposure with ease.

FAQ

Q1: When should I use the 3-foot DTS CAN harness?
When the standard DTS connectors won’t reach cleanly between modules and a longer link is needed.

Q2: Does this harness include resistors?
No. It’s a non-terminated harness for systems that already have proper CAN termination.

Q3: Will it change throttle or shift behavior?
No. It only carries the CAN data—DTS operation stays the same.

Q4: Can this be used outside DTS systems?
It’s designed specifically for yellow 10-pin DTS SmartCraft connections.

Q5: Is installation simple?
Yes. It plugs inline using factory connectors and routes like any DTS cable.
