99 Bravada vacuum line

Hello to everyone. I am new here but have read your forum through different problems I have had. Now I come to you in need of help. I had a problem with my air flow changing for my heater when I went up a hill. I read that the problem was a vacuum leak. Tonight I found the leak. If you face the motor from the front there is a " T " to the extreme driver's side with 2 lines going off of it. There is a short line that goes into the plastic hose that contains wires. The second went straight down toward the wheelwell. The short one was broken and I fixed it. But in the process I accidentally pulled the other loose from a connector that went around the wheelwell. I cannot find the other line it connected to. Someone said they thought it went to a canister in the wheelwell. Does anyone know if this is true ? I put a screw in the end of the open line. If there is a canister in the wheelwell then the line I disconnected supplied the vacuum from the motor to it.My concern is that there may be other lines going from the canister elswhere that needed that vacuum. Will it hurt anything to run it like this ? I don't have any vacuum diagrams. The Hanes manual I have doesn't have any.

Thank you for your help !

There's a nipple under the ABS pump bracket that the vacuum line attaches to on a 2000 S10..

That is exactly what I hoped. After Church this morning I looked at another Bravada and felt where it led to and hoped it was just attached to a nipple on the side. Thank you very much for confirming that for me !!!
