1996 5.0 turbo

[1935explorer]

I’m trying to figure out how to hookup a Holley sts pcv switch and check valve but I’m confused. It’s for a 1996 Ford Explorer 5.0, this is what directions say in attachment and I can’t figure out the where fresh air source comes from ? Or other sources ?
1. Fresh air source – This port will typically be between the MAF sensor and the throttle body.
2. Crank case port #1 – This port will be hooked to the fresh air source.
3. Crank case port #2 – This port will be hooked to the intake manifold port.
4. Intake manifold port – This port will evacuate the fumes from the crank case under non-boosted driving

I’m your intake tube between mas and throttle body is the crank case breather. It attaches to the oil fill spout, seems like that is where the instructions are telling you to put it. Fresh air is from the air tube side, crankcase is in the oil fill side
