4AGZE mechanical boost gauge

[Skein]

OK I feel like a retard.

I can't find a small vacuum line that is AFTER the supercharger to tee the boost gauge vacuum line into. Every line I try gives me vacuum not boost. Are there no small lines like the ones before the SC? Do I need an adaptor to fit a larger line somewhere? I'm lost.

The ones which come off the intake manifold are the ones you want, not the ones coming from the throttle body.
Also remember that free revving at idle wont engage the supercharger, and hence wont show boost.

There is a small line coming vertically off the manifold, I think it's near the inlet. That's the one you want.
