Minor Versionm

by Noah Thatcher


There are two modules which need to be installed:

-OBD programmer module using T-harness connected at OBDII diagnostic port. This module can be removed after programming

Programming procedure:

The programming procedures must be done using Xentry

    • Using provided OBD T-harness, plug programmer module in line at OBD plug

    • Once module is connected, confirm that the LED is solid. If LED is flashing, the programmer module has already been locked to another VIN

    • Follow steps in video for programming procedures

    • After running procedure you may have a message saying that it failed- this is normal. Programming should still have taken

    • Once programming procedure is run, the OBD T-harness and module can be removed

    • The OBD module and T-harness should stay with the vehicle in case programming ever needs to be performed again

    • Using pry tool, remove panel at end of knee bolster

    • Remove two screws and panel and end of footwell

    • Be sure to pin CAN high/CAN low into spots where factory CAN high (pin 17)/CAN low (pin 7) were removed

    • Remove adapter from end of provided CAN plug. Factory CAN wires will be pinned into this plug

    • Insert factory brown/red CAN wire that was removed from CAN B plug into pin 1 on adapter

    • Insert factory brown CAN wire that was removed from CAN B plug into pin 2 on adapter

    • Plug adapter with factory wires into 2 pin CAN plug on provided harness
