87 300E. Which vacuum diaphram is which?

[lizem100]

I have some air flowing from the side vents even with the AC control on "O."
I pulled the glove box and see no obvious broken disconnected lines. The hoses come out of a manifold on the left and are numbered from top to bottom 1-6. If I test the hoses with a vacuum I need to know which diaphram fits with which number. Is there a picture of the setup?

My experience is with the 190E, but in ours '0' simply turns off the fan, it does not disconnect the vents. That is done with flapper controls at each vent.
