Hey Guys, Off to a great start here.... I know what "off" and "on" is, but can't seem to recieve these codes.Called the local Dodge dealer, and the service dept. tells me it can't be done on my truck.(07' ram 4x4 2500 6.7l, Big Horn addition).Am I really this stupid, or am I missing something here?Thanks for your speedy replies, and warm welcome....
