95 3.0 V-6

Hi All.... I just bought a sweet rig, but for some reason, the fast idle warm-up valve is caped-off. I know it should connect to a vacuum switch - stemming from a coolant temp sensor. But I can't find where it may have connected.

A picture or diagram would sure help. (Yes, I've read the sticker under the hood, but can't make sense of it).

Thanks much for any direction ( :
