i took everything out to get my heads off and now that im putting everything back on, i found a plug that i can't plug in anywhere - or atleast i can't find where it plugs into. i dont remember ever taking it off, so maybe my old mechanic had it hidden because it wasn't being used anymore? i dunno... here's the picture... let me know if you can figure out what it is and where it goes. i found it behind the dist on the pass side near where all the cables go into the firewall... maybe it has somethign to do with the smog system that i had taken out a while ago and forgot about? thanks guys

 

Looks to me like the EGR solenoid.

 

Looks like the infamous "connects to nothing" plug.

I found mine a couple of months back. This thread will explain all.

I think that one connects to an extension harness that then plugs into the IAT on the bottom of the plenum.
