I am putting another engine in my '99 Cavalier. Got the new engine in, trans etc. Had all the connectors labeled, or so i thought. Can't find where this one goes. The blue arrow shows the cable harness it comes from and the other connectors from the same harness that go to auto-trans. I'd appreciate the help. I'm just blind I guess. I thought it came front the underside of the trans but can't see it.
