[V8] vacuum color code on swithc for 87 quattro 5000

[chris brown]

I had to take the main vacuum switch out of my 87 quattro last night to work on my radio. And now i do NOT have the color code for the 5 hoses that attach on the back of the main switch on properly. I have the car now in front posi mode and it wont disengage. I think i have a couple hoses reversed. Does anyone know the proper color code for that switch.  The rear wheels engage and disengage fine. 
 
 thank you in advance to whoever can help out. I didnt really have time to take it all back apart. I might as well get the right colors first, then take it apart again.
  Thanks Chris
