well you actually already have a blow off valve stock (assuming you have a TT). The stock blow off valve is a piece of junk, but its a closed blow off valve. Depending on what kind of blow off valve you have (open or closed) will determine how its hooked up. The stock blow off valve is located underneath the intake T pipe. If you dont know where that is, look for your air filter. The next piece after your airfilter is your MAS, where the wiring harness plugs into. The MAS is then connected to the intake t-pipe, and the stock blow off valve is underneath. If you have a closed bov, it will need to be installed the same way that the stock one is. If you have an open bov, it will need to be installed almost like the closed bov, except nothing connects to the intake t-pipe. You will need to find something to plug that up that wont get sucked into the intake.
