I have two of the diagrams "blown up" to about 14X24 and laminated in plastic. I can use erasable markers on them. Also , I HAD at one time all of Kiwi_Roy's diagrams printed off . They are in color w/footnotes along w/V readings where needed. I could NOT find the headlight diagrams . I remember having them because there are two "styles" , earlyish and lateish ! There is a difference in them n I can't remember . It was silly whatever it was .
I am going to have to search my folders here and find them or search this forum again and find them . He is offline here and has been for sometime. I reached out to him and never got a response . I wish him well !
BTW , I leave German automobile wiring diagrams alone . I last tried one on a M/B retractable hardtop. Got an American version and was able to understand it w/o any troubles.
