Throttle Body help needed

[rangernystyle]

Ok so i have a 1994 ranger with a 4.0 that i have been working on and putting together and i was wondering if anyone could tell me what connects to the fitting on the bottom of the throttle body, it looks like a vacuum line of some sort should hook up but i cannot find anything. Any thoughts, pics, ideas would be appreicated.

I have a 98 4.0, on my truck that hose goes to one of the emission control devices that is mounted further up the driverside inside fender from the brake booster and stuff like that.
