AC/Heat Actuator Vacuum Lines

Hi Members. I posted this question in the Heat/Vent/A.C. slot of our forum, but did not get any response. Maybe I will get a bit more exposure here. I marked my vacuum lines when I disassembled my A.C. and heat boxes from my 65 Dart GT Restoration. Unfortunately, the markings/labels became lost since the time of removal. Now, during assembly, I became somewhat confused where these pneumatic/vacuum lines should be attached to the actuators. I did some research on line, and what I found was that the RED stripe vacuum line attaches, always, to the rod side of the actuator. Can anyone confirm this? Thanks for the help. sgrip65
