B5 CCM Wiring

Comfort Control Module  (CCM)  Wiring  and Function B5 (From  yr 2000)

 

There is lots of information on the web about lifting wet carpets and drying the CCM under the front passenger seat.

This information is to help with the actual plugs, wire colours and functions of the wires.  Not all CCM will have all wires and all functions and some changes occurred over the years.

If you have lost a function, the function list will give you a clue about which wire or connector to check
