I'm looking for a PDF, or possibly a website, that had the steps for correctly adjusting the Marelli linkages and microswitches. I'm helping a friend on the other side of the country get his new '90 acquisition up and running.

About ~1.5 years ago, I remember coming across one somewhere here on the forum. It was a probably ~5 page document detailing exactly how to do it, with very good clear pictures of each step. I've been searching for it for the past several hours, even looking for the file on my old laptop but to no avail.... Does anyone remember what I'm talking about? It could have possibly been a webpage, but I definitely remember printing it out and using it (unfortunately left the guide in the trunk of a parts car I sold, doh!)
