Poking under the hood of the wife's 98 Zetec, there is a hose right next to the battery (looks like a vacuum hose), to the left of it if you are standing in front of the car. I noticed the other end wasn't plugged into anything... so who knows if it somehow came off, or more than likely I pulled it off without knowing it. Can anyone tell me where the other end is suppose to go into? I can't find it at the moment.
TIA
