Blow off valve question

Hey guys we just finished installing a d1sc procharger with twin intercooler on a 98z28. Since I purchased this kit used I think I am missing something here. I noticed on pics here with this same set up that there is a line connected to the blow off valve and runs to the engine. Can somebody help me out please on how this connection runs? Any pics would be good too. Thanks!

it's a vacuum source for the blow off to well.. blow off.

"tee" it to an existing vacuum line on your engine, fpr, air, whichever line you want.

Don't tee into the line going to the horn vacuum canister as it has a check-valve that will yield vacuum. I learned the hard way that this will hang the bypass valve open at all times.
