If I go this route I need to change the throttle body need the tac module and pedal set up and that should be it for the dbw isnt it? I've already had nelson tune my pcm for drive by cable and its the red and blue connector the 03+ dbw is green and blue isnt it will my other pcm still work or will they need to swap it out for the right one or will they even swap it out I wonder
