The optional wiring control unit CCO is located on the right side of the cab, on the rear post of the front
passenger side door.
Depending on the version and the structure of the vehicle for the coach work fitter versions, this
control unit may feature one or two modules and an additional socket known as a "transformer socket"
(or "bodywork socket") - P125 in the wiring diagrams. In addition, in the compartment where it is
housed, there may be additional components (fuses and relays) for specific functions relating to
