I have the 4 vacuum lines hooked up to my blend doors, but a black one disconnect and don't know where to reconnect it.

The black line should go to the engine vacuum source which also attaches to the vacuum reservoir under the hood. With the engine running just listed for the hiss from the vacuum leak.
