OH...

I see what you are speaking of...

It's your IAC valve tube... and I would REALLY expect any cold air kit to have one...

You should have 2 hoses up there:
The IAC valve tube, and a ventilation tube

You should be reconnecting BOTH hoses.

Here is a pic of the correct unit for your car. Also note that there are installation instructions on that page also.....

When installing, don't forget your IAT and MAF connections either!!!

Hope this helps...
