Right, I'm a little tired & pushed for time but to start you off a high idle & old looking vac. lines points me to the power steering idle up valve & it's lines.

If you look under the accordion hose (between air filter & turbo) there should be a 90 degree elbow with a vac. hose on which should be attached to the pas idle up valve on top of the pump, can be a little hard to see if it's off but it's round & has 2 vac nipples on top. one should go to the accordion hose as i said, the other runs round the steel pipe on the front of the engine about halfway down behind the fan belts, and then goes back to rubber and into another steel bunch of pipes. I can't remember 100% how it all goes but the tsrm helped me put my vac. system right along with some photos from another member which I'll try to find before I go home...

hold on a sec...
