When i was working on my throttle linkage yesterday, my vacuum stuff came loose, causing my car to continue running with the key off. the culprit line is a black line from the blue resevoir(?) on the drivers side fender than funs down in behind the engine. what does it plug in to? i need to fix it so i dont have to pop my hood 20 times tomorrow to shut off my engine!

Nothing. The black line is a vent, and initially runs into the cabin (for cleaner air). I would look elsewhere for your answer. You must have knocked something else off.

Brown lines on my 1980 and 1983.
Two brown lines go to key switch.
These two lines complete the circuit.

Make sure they are snug at the key (under dash) first.
