Bypass valve hoses atmospheric vent

Hey just got a supercharger put on, no major issues, noticing everyone else has there bypass valve houses a little different then mine.

I know being a force inducted NA car, one port is atmospheric vent now, the other port should be going into the supercharger, but should that be the top or bottom nipple?

At rest the bypass butterfly valve is closed. You can see in this picture that when there is (V)acuum on the top of the actuator diaphragm it will pull the rod up/in which opens the valve to allow air to circulate to prevent the supercharger from trying to suck air through a partially closed throttle body. The bottom portion will do the same thing when pressurized. The LSJ solenoid will route boost pressure from the IM to the bottom port when the ECU detects issues and commands it to pull boost.
