    I just did this and it was not that hard. just carefully remove the auto plug and the plug for the auto brain and make sure you connect the brown/black wire pin 26 transmission ECU” need to be connected to any “red/white wire on the main relay.

        You dont need to do anything, Just let it alone and it will work just fine the way it is.
