Mercury – CAN Data Harness (10-Pin, No Resistors) | 2-Foot DTS Lead | 84-879312T45

Overview

DTS networks often need a little extra reach to land a clean, strain-free connection between modules. The Mercury 84-879312T45 CAN Data Harness adds two feet of non-terminated SmartCraft length, carrying CAN 1, CAN 2, and CAN 3 signals through a standard yellow 10-pin DTS connector. It’s made for setups that already have proper termination elsewhere and simply need a longer, stable data link to complete the rigging.

Key Features

• 2-Foot CAN Extension – Provides more routing room than the 1-foot lead for flexible DTS layouts.
• 10-Pin Yellow DTS Harness – Uses the standard DTS SmartCraft connector with all CAN lines active.
• No Built-In Resistors – Intended for systems that already have proper CAN termination installed.
• Full CAN Path – Supports CAN 1, CAN 2, and CAN 3 communication channels.
• DTS System Ready – Designed specifically for Digital Throttle & Shift SmartCraft networks.
• OEM Connector Fit – Snaps in securely with Mercury’s factory-style pin alignment and shielding.

Compatibility

• SmartCraft DTS applications
• CAN 1 / CAN 2 / CAN 3 SmartCraft networks
• 10-pin yellow DTS harness points
• SmartCraft CAN Bus components

Performance & Practical Benefits

This extension gives DTS installations a clean way to bridge slightly longer distances between modules without stressing the original harness. The extra two feet make routing smoother through tight chases or behind larger helms, and the non-terminated design keeps the network’s existing resistor layout intact. Once connected, CAN communication stays steady, helping DTS controls and related SmartCraft devices respond reliably.

Why Buy OEM

DTS systems rely on accurate CAN signaling, and Mercury’s OEM harness maintains proper pin alignment, shielding, and build quality. Aftermarket cables often struggle with loose fittings or signal noise, which can cause intermittent DTS behavior. The OEM harness provides a dependable, long-lasting connection that holds up to vibration and daily marine use.

FAQ

Q1: When is the 2-foot CAN harness a better choice than the 1-foot version?
When the modules sit slightly farther apart and the shorter lead won’t reach cleanly.

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

Q3: Will this affect throttle or shift response?
No. It simply carries CAN data between DTS modules.

Q4: Can it be used on non-DTS systems?
It’s intended for yellow 10-pin DTS connections specifically.

Q5: Is installation straightforward?
Yes. It plugs inline with factory connectors and routes like any other DTS cable.
