Here you go.

from the bottom lever the longest goes through the firewall out to the mixture flap and inside to the temp control lever usually on the bottom

the second longest goes from center lever to the flap control in the center section of the ac box that flap also hits the switch thats inside the airbox that turns on the ac compressor

the shortest goes from top lever(which controls defrost and floor heat) to the part of the ac box located right below the ac control to control the defrost.
hope this helps
