97 deville heat/ac vacuum lines
 

HELP!! My idiot friend tried to "help" me with a defroster issue. He moved around a couple of the vacuum lines under the drivers side to the vacuum servos. Dosen't remember which ones go where....4 colors red yellow orange and blue. Just a pic or diagram would be helpful. I've googled this to death and not one piece of info. I always do my own work and this cements that argument...lol
Thanks for looking.

Anybody got a suggestion?
