Well I partially answered my own question. The emissions diagram on the front of the engine compartment says that goes to ACSRY. What that is, I do not know. I also found that it goes to (comes from?) a "T" connector. On one of the branches is this hose, on another is a small hose that goes to a wiring harness, and on the other is a hose that is broken off but looks like it went inside the front fender, driver's side.
The hose that goes to the wiring harness looks like it goes through the fire wall (!?), but I was unable to track it with the wrapping on the harness, and the brake cylinder is in the way.
The hose that goes into the fender *may* have come from a black, round, plastic piece secured under there, about the size of a canteloupe. That also has a hose broken from it that seems like it may have come from the "T" at one time.

SO, does anyone have any idea what all of this stuff is? Haynes doesn't say.
