It's attached to a vacuum line and has a power and ground wire also attached.

The vacuum line that attaches to it broke and I would just as easily get rid of it.

 

are you referring to the silver canister,,, that looks like something someone added,, if so it looks to be some kind of sending unit, are you sure that it was a vacuum line going to it, or possibly a fuel line,, looks like a fuel solenoid for a nitrous kit in the pic,, if it is then that may be a low fuel pressure safety switch for the nitrous system...

 

The one with the blue connector is for the A.I.R. system
