my problem is upon ressembly I have more hoses than nipples for the small vacuum lines, one is the device located right next to the IAC valve, it is black, takes a two connector plug, fastened with a single 8 mm bolt into the intake casting, (it is a solenoid), one line loops back and down a few inches to a metal line under the intake runners, the other line has a longer hose that I cannot figure out where it goes. There is also a device mounted on the passenger side inner fender that has a line which is different than other lines, sort of a grey or green color with looks like an inline filter, I have no clue on that either, again any help much appreciated....thanks

pictures too!

thanks Mike, it's becoming clear, good to know what these devices with the connections are called and what they do, I did an engine pull and there may be a "T" in my rather large unused parts bin
