Found a few things that are in hooked and also one has a bolt in a hose????? Any advice helps. Passenger side by coolant tank
Down behind altanater
Front driver side by battery
Random hose with a bolt in it.

 

not sure what that connector is for... I wonder if it was asssociated with the air conditioning, which appears disabled (there's no belt on the a/c compressor in another pic)

not sure what we're looking for here?

ok, that is the charcoal evaporative cannister, and that hose fitting either goes to a vacuum line off the throttle body or intake manifold, or it goes to the gas tank vent.

on the 1991 turbo we had, my pictures show that fatter vacuum hose near the bottom of this pic goes to a "T" and has a couple things coming off it, including the brake booster, adn the vacuum line to the HVAC controls under the dashboard. this hose with the bolt might have been the one to the charcoal canister.

 

Electrical plug, probably not used.
Canister hose goes along the other one to the throttle body, I think I see it laying loose under the battery cable.
The hose with a bolt in it goes to the plastic nipple that comes out of the vent hose coming out of the oil separator-- nipple probably broke, they plugged it...
