DBW Pedal different than engine/harness/computer

[Critter]

It seems there are 2 different types of setups. One with a somewhat normal looking foot pedal and the other with the alien looking solid plastic thing. They will not directly swap, at least without doing some repinning. As far as what applications got what, I haven't determined the pattern (I'm sure somebody has). But I do know that my Dad's 2005 5.3 work truck has the "normal" dbw pedal but my 2006 2500 6.0 pedal has what I call the "alien" looking pedal. In other words they wouldn't directly swap. It is possible that if you swap pedal AND keep its matching tac module that you will be fine, I'm not sure about that.
