1983 300D Turbo - Automatic

Would like someone with a good eye to see if this vacuum setup works or suggestions how to clean it up.

Notes:
-EGR, Vacuum temp sensor are plugged with vacuum caps. 5way on top off valve cover is bypassed.

-Central locks disabled, HVAC disabled.

-Overboost valve: Top port goes to ALDA, bottom port connects to rear of manifold banjo.

-VCV: Top port goes to transmission, bottom port connected with black hose goes to cabin, as a vent.

I’m mainly concerned with the mess above the VCV. There are many 3 way connectors that lead to know where.

I’m getting proper vacuum tho, I believe (I don’t remember the vacuum acronym) 24 vacuum and 16 from transmission.
