It will be ready to go once you get it. just plug it into your truck, but have a paper handy to write down your HEX code. It will pop up on the screen shortly after it turns on. Make sure you follow the instructions and have the key on when the you first plug it in, but make sure the motor is off! once you have your hex code, submit it, and you dont need to worry about pegasus until your custom tunes are sent to you.
