wat does this connect go to?!

I believe that is suposed to go to the diverter valve on the tubes that help with emissions that go from the air pump to the back of the heads.

Either coolant temp sensor or something else that plugs into the lower intake... Air temp sensor.

Or the one above... I don't have one of those.

Mine is hanging out like that as well.

THere are 2 coolant temp sensors, one on the metal coolng/heater core lines, and one in the intake itself. The air temp. sensor is on the drivers side of the intake and is wired in with the injector harness, so it should be between the first and second injector on the drivers side, not the passenger side. The passenger side has two plugs almost identcal in with the injector harness and one goes to the temp sensor and the other to the diverter valve wiring for the emissions.
