The vacuum hose you need to T off of will be the one that you tapped in your intake plenum that plugs into the blow off valve. Essentially you want a vacuum source after your throttles.

You don't need to wire a scramble switch, nor do you need to wire the RPM/vehicle speed sensor/throttle signal wire if you don't want to use these features. Just tuck them away so they don't short on anything.

Hopes this helps.
