I must be the least observant, or least intelligent person that has graced (or lacked grace) on this site, but for the life of me I can't find the other end where this hose was supposed to connect. I searched - visually and by running my hands over the underside of the intake manifold and what I could see of the throttle body, but I still cant find it! I found three other vacuum lines - all in good shape - all still faithfully connected to the other stuff they've always been hooked up to.

I even looked at the link to the schematic diagrams - no luck.

Any more descriptive on where this mystery fourth vacuum nipple is located. I am befuddled!
