Product Description

This compact adapter easily converts the Green 9-Pin connector in your vehicle to the Black 9-Pin connector on your data link adapter cable. â€‹Made with a genuine Deutsch connectors and over-molded construction this is a quality adapter.
Several older model datalink adapters only support a single CAN data bus at 250K. However, the 2017 vehicles have increased the speed on CAN1 from 250k to 500k rendering your old datalink adapters worthless.  Our connector allows old CAN1 250k datalink adapters to still communicate with 2017 vehicles by crossing over the CAN1 data lines to CAN2 on the vehicle.


  • Extend the useful life of your single CAN datalink adapter to 2017 vehicles and beyond
  • Connects Black 9-Pin Deutsch on the datalink adapter cable to the Green 9-pin Deutsch vehicle connector
  • Supports CAN1 only
  • Compact, durable design
