How does it hook up and does some one have a link that shows how it hooks up and what it does. I have seen a small picture in a mag. but that is about it. If it is so great why isn't there tons of info on it. No flame to the product just wondering. I am looking at modding the car but I hate chips and using the service port. That just says void my warranty. I have enough trouble getting the dealerships to fix the stuff on my stock cars. I do not need to give them an excused to void the warranty on the modded car.
