It may be due to a language barrier, but I find the original post on this thread rather abrupt. It does not encourage me to use my time and knowledge to assist the OP. The inclusion of the english word "please" would have helped.
However to be magnanimous, further information is required.
There is not a single wiring diagram for the whole vehicle, but many segregated according to the functional area.
What part of the vehicle is OP interested in?
Is the vehicle an xxx230, or an xxx244? (See VIN number/plate.)
If the vehicle is an x244, the following link may be usefull, but eLearn does contain errors.
