I just put a new engine into a 03 explorer and have ran into a couple of issues. First off I am having troubles finding where the red and black vacuum lines on the passenger side plug into. Second off ontop of the throttle body is a idle air control valve. Where does the vacuum line go off of it? And finally There is a small coolant line coming off of the top heater core hose that goes by the oil filler and I have no idea where it goes from there because someone cut it. Can anyone please help me

Okay after going back out into the shop to check and see where im looking at I realized that the vacuum line im talking about is actually on the intake manifold right behind the IAC. Its a hole in the back side of the intake manifold with a piece of hose about 5 inches long I figured out the other vacuum lines I just need to find what this hooks to and ill be done
