Here's a link to a Czech site covering most models but has a small Xm section. Wiring diagrams and parts info available for downloading.

i had seen the diagrams on this site but gave up trying to use them for what i was doing due to my lack of foreign language skills.

are these diagrams available on your CD, but in English, Noz? In particular the electrical ones?
