Did you go on the attitude website, that is where I found mine a couple of days ago. Also when you install it to the instruction on there website, don't hook up the power wire for your box to the red blue wire in the ecm plug. You will see what I mean in the instructions. If you hook to that wire you can run into issues with stealing to much power from the ecm, and will not rev out. there are two red wires coming off a white plug over the voltage regulator, you can take power from one of them. Justin from Silber told me this because I had this problem. If you want more info or pictures of my hook up I will gladly e-mail you.
