The Mercury Quicksilver 879968T6 is a genuine OEM 6 ft. SmartCraft CAN P data harness for non-DTS SmartCraft systems. It uses a blue 10-pin connector and carries the CAN P data circuit along with network power and ground conductors. It contains no termination resistors and no additional horn or Link Gauge connections — it is a straight data-link section cable, not a terminated network endpoint.

Compatible Applications

• Mercury SmartCraft installations using the blue 10-pin non-DTS CAN P network
• Direct data-link connections between compatible SmartCraft components including:
  • SmartCraft junction boxes
  • SC1000 / SmartCraft instrumentation displays
  • Compatible Mercury or MerCruiser SmartCraft engine connections
  • Other CAN P components in a correctly configured SmartCraft network

Fitment & Network Configuration Notice

Confirm your SmartCraft network type before ordering. This harness is for a blue 10-pin non-DTS CAN P system and contains no termination resistor. A correctly configured CAN network requires proper termination arranged elsewhere in the system. Do not substitute this cable for a visually similar SmartCraft harness that includes one or two termination resistors — doing so will change the network termination configuration.

When to Replace

• Connector pins are bent, corroded, or damaged
• The cable jacket is cut, crushed, or badly chafed
• Water intrusion has damaged a connector
• SmartCraft communication is intermittent and cable testing has identified this harness as the fault
• The original cable is too short or has been improperly routed
• A SmartCraft installation requires a 6 ft. non-terminated CAN P extension section

Diagnose intermittent SmartCraft faults before replacing the harness — poor termination, junction-box connections, and other network components can produce similar symptoms.

Installation Notes

• Disconnect battery power before servicing any electrical connections
• Verify the installation is a blue 10-pin non-DTS SmartCraft CAN P system
• Inspect connector pins and seals before mating the harness
• Route the cable away from sharp edges, excessive heat, and moving components
• Avoid tight bends or tension on the connectors
• Secure the cable using the original routing and support points
• Confirm the network already has the correct termination resistors in place — do not add terminators simply because this harness contains none

Technical FAQ

Q: This harness has no resistor — is that correct?
Yes. The 879968T6 is specifically designed as a non-terminated data-link section. Termination for the CAN P network must be provided by other components (such as a terminated harness or junction box) elsewhere in the network — not by this cable.

Q: Can I use a longer version if my routing needs more length?
The 879968 family is available in multiple lengths (T10 through T50). Verify routing requirements against your SmartCraft network layout and use the appropriate length — do not coil excess cable.

Q: How do I tell if my system is CAN P vs. another SmartCraft network type?
Consult the Mercury SmartCraft installation guide for your engine and instrument model. The blue 10-pin connector and non-DTS designation are key identifiers for the CAN P network used with this harness.

Parts Desk Insights

The critical detail with 879968T6 is not just its length — it is a non-terminated CAN P harness. It carries no resistor, so it is intended for installations where termination is already provided elsewhere in the network. A visually similar 879981- or 879982-series harness changes the termination configuration and should never be substituted by appearance alone. The most common ordering mistake is selecting a SmartCraft harness by length or connector appearance without confirming the termination type — incorrect termination causes persistent CAN network faults that can be difficult to diagnose after installation.
