Please choose between CAN or Analog.
IF YOU HAVE A CAN BUS CAPABLE ECU: The CAN bus harness provides a much easier installation as all the data required for the TCU will be received via CAN communication from your ECU aside from brake switch.
IF YOU HAVE STANDARD ECU: Will require more in depth but not complicated wiring for the TCU to see the required fields allowing the TCU to control/operate the 8HP transmission.
