hmm your harness might be different than a 94+ but i'll guess fuel pressure regulator.

I can't think of any vacuum line that is in a wiring harness that goes under the brake booster. The only thing I can think of that you might be referring to is the EVAP canister vacuum line that is wrapped with the fuel supply/return lines. They go under the car, under driver's seat and have a connnection there.

That looks like the line for your pissers. Make sure your windshield washer sprayers are spraying

Not really a good idea to post a pic that large in a thread.... really screws up the layout. Just post a "link".... I edited it that way.

It goes down ( From where yours is broke ) behind the clutch fluid resevoir, and into a thick wiring harness. It runs through the harness to the front of the car, and comes out by the core suppot and into the washer fluid pump.

The other end of it should go up into the cowl, either through the firewall then up, or up under the cowl and then over to each pisser.

Re: broke a vacuum hose..where does it go?

yeah thats exactly it. So if it stays broken...i should be fine? as long as my window doesnt get dirty. As long as its not a vacuum leak.
