take cover off top of intake. Look at where the TB attached to the upper plenum. there will be a peice attached by two bolts just behind the TB with an electric motor attached to it. It is located on the back side of the plenum closest to the fire wall. There will be a tube running from it to the intake tube going to the TB. If you still can't find it post and I am sure that someone on here will have a pic or be able to get you one.
