Series III vacuum hose routing for brake booster

Hello Folks,
I forgot to take a picture before replacing my brake booster. There is a hose that goes from the reaction valve to the vacuum plenun and one hose from the plenum to the booster. Which one goes to the top inlet port of the plenun and which one goes to the bottom. I know the function is still the same but what it to look right.

Thanks

If you get it wrong you will have no power brakes. Ask me how I know. Here is the diagram for a '66 S1. Not sure if it is the same as yours. I just replaced the MC, Servo, and Booster on mine a month ago.

And here is an extract from the Repair Operations Manual for the Series III
