There are several references in this forum regarding manual sunroof: install, re-build, etc.

I got my cables from BavAuto and followed his detailed text.

And here's a good parts reference:

I just used it to "see" how the rear weatherseal is installed.
OK, I had to look closely, but it proved useful.
