JRSC Bypass Valve

Does the bypass valve on a jrsc get its signal line from a vacuum only source before the supercharger or a boosted source after the supercharger? Thanks.

I think all our vacuum lines are in intake manifold so should be after JRSC...you won't have ani boost before him so it'll stay open all the time

The actuator itself has a spring in it, so when there is no vacuum to hold it open, it automatically closes. I just replaced it because the old one had a tear in the diaphram. Jackson Racing are no longer selling these kits for the SVT focus, so I couldn't look up the instructions on their website. I was just wondering if you fed it boost if it will tear the diaphram again.
