E30 Cabrio power top photo request

[bostonbmw]

I am trying to get the power top functioning on My 91 cabrio. I have a bag of parts from the previous owner which seems to be missing some parts.
I have tried looking on realoem but can’t find a good diagram. I am looking for some photos with the top in the up position inside the top storage area I need to see the linkage and cable system. Also what is the function of the cable and pulley on the left side of the trunk?

THe cable that runs into the trunk is there to stop you from opening the top with the trunk lid open.
