The green wire with the blue connector on the right side of the pic...wut is it supposed to be connected to? I noticed it dangling underneath the glovebox the other day and figured it must've came loose from something. Can anyone help? Thanks

 

Diagnostic port. When you're getting a Check engine light you complete the circuit with a paper clip or wire to find out what code you're getting.

 

And for your future reference a list of codes:

So it's not supposed to be connected to anything right now? It would be alright just to tuck it back underneath the glove?

 

Yes, just tuck it back under the dash, but keep it accessable so when you throw a code you can easily get to it.

 

Thanks for the info and quick responses.
