What are these for? the black thing is on the passenger side of the car and the red wired plug is on the drivers side. The little black tube that is circled on the second pic does not seem to go anywhere. Should this go somewhere?

Thanks

 

First one is EGR solenoid. Second one looks like O2 sensor wire, but I don't think that's the harness loom it should be in.

 

Then im assuming those are vacuum lines for the solenoid? One of them is hooked up but the other is not.

 

One of those vacuum lines goes to the ERG valve, the other to a port on the bottom of the plenum.
