Ok Guys, I need to know the route for the vacuum lines to the heater. View attachment 20350 Which nipple does what? I really want to know this so I can get my heater controls working. My car has a 200 motor and originally had A/C, but was taken out. I know the controls use vacuum, but I don't know how to hook it up. Help would be MUCH appreciated!
Had this old link bookmarked...see if it helps any... http://www.geocities.com/cping3/WiringDiagrams.html
On that canister....the big nipple goes to manifold vacuum. The little nipple goes to the AC controls. The vacuum lines are color coded with a stripe. You should be able to look those up in a Ford service manual.
