EDIT-----------IGNORE THE ORIGINAL POST It may be that the 6C (which is CD) is DIFFERENT than the 5C and that the 5C MAY be inductive more like the original Mopar ECU See this page 35

I DO NOT KNOW YET if this is correct but found one post that claimed that the 5C was a 'direct plug and play' for a Mopar box. If so it is DIFFERENT than a 6C (CD)
