To the best of my knowledge there isn't a single "diagram" for the CCRM. The CCRM is noted when it is part of a sub-system. For example, engine controls, AC, Cooling fan, and the like.
There is a diagram for the CCRM connector. However, it does NOT tell you what the individual wires do.
Do you have a particular question you are trying to answer?
