Cruise control hosing

[Andrew Sitzer]

Hey all, I am trying to reinstall the cruise system in my 86 5ks nonturbo.
(All the hoses were ripped out by somebody other then me :)
Anyways, looking at the picture in
http://www.humanspeakers.com/audi/cruise-diagram.htm is very helpful...
Quick question though, my car is autotrans.. is there still a connection
(labeled #5) to the brakes?  (Id imagine there has to be for the venting
of plasma, i mean air... But I just cant seem to find any stub where it
would connect to... Is it on the brake pedal itself? Is there some sort of
box?

Thanks!
