I don’t have the B+B Fusion, but have a custom setup which is very similar using
DynoMax UltraFlows w C6Z06 NPP valves. If using on a 91-95 ZR, THERE’s a vacuum line from the motor going to the charcoal canister in the passenger rear corner. I’m using that line to feed vacuum to the valves w a check valve. Also installed electrical switch in line for on demand closed/open.
I believe mike100 former ZR used micro switches to control opening based on MAP and rpm.
