I really expected it to be more complicated. I opened the box, plugged it in the OBD II port and started the truck. That's it. Done! No more 4 cyl. mode. I'm not sure why they put LED lights on it. They illuminated my ankles at night so I had to put a piece of electrical tape over them, problem solved.
