You can use the search feature to perhaps find the graphic, using "schematic" as a key search word. Or you can read the first interim report
here, and a short second interim report at the same site, both available in English.
I think it is short-sighted to state that the R2-5 relay was "at fault" even though we may know that the TOWS did not perform as designed. A similar claim regarding the Radio Altimeter is made for the Turkish B737 accident at AMS - it may have been a factor, but other, more serious issues were also involved. The logical conclusion to such a proposition is to "focus on MD80 R2-5 relays to ensure their contacts are clean and that they're fastened securely", etc etc, when often these things are far more complicated and causal factors more deeply hidden than first appears.
Checklist interruption, already discussed above, is one such factor. A standard SOP for any interruption during the use of memorized checklists for example, is to start them over again from the beginning. The only exception to this is when using a mechanical checklist where open items may be clearly seen and not merely remembered as "not cleared".
