310 Vacuum A/C controls

Greetings! I am sorting out some issues with our 1983 310 A/C control system and I am unable to find any information on the vacuum lines at the back of the Chrysler sourced panel. The A/C system itself was made by ARA, which is long since out of business. Some of the parts are available from ACME A/C. I was able to find a new Chrysler vacuum control head of the same part number by googling it. I only can find 4 colored plastic tubes that connect to the panel via the translucent vinyl block, and I suspect they may be in the wrong positions.

Here's what I have determined using a hand vacuum pump:

Orange...defrost vents
Sky Blue...recirculation
White...dash vents from engine/reserve sphere

Should there be another, say for floor vents? There is one more opening through the translucent connector. If so, where is the floor vacuum damper?

Any clues/facts would help.
