Hi, I finally got my engine into my 86 runner but I have a small issue, there are two vacuum valves mounted on the valve cover that I can find where to connect all of the lines. The chiltons and haynes manuals are of no help at all because you cant trace all of the lines from the diagram they supply. I know one is for the AC but no idea what the other is and I havent a clue as to where the hoses on either belong. Can anyone help me?
