  3. Connect the Y-cable's single connector to the vehicle's J1939 port. Push firmly until fully seated.
  4. If applicable, reconnect the existing device to one of the Y-cable's split connectors.

  5. Connect the standard J1939 Install Kit (9-Pin) cable to the Y-cable's remaining split connector.
