This brings up a question I had not considered: how does the convenience relay know when the window is fully open when you press a front window switch all the way to "auto down?" I'll have to look at the diagrams because I don't know how that works.

Thanks for asking!

Interesting. I've often wanted to incorporate this feature set into one of my 126/124s cars but not knowing when to stop makes it difficult. I mean, you could use limit switches for auto up/down... That would be annoying, installing/mounting/wiring 8 switches in the doors. Current sense/limit would work better/easier. Current draw should increase when the window hits the top/bottom, soon as that current spikes up cut power.
