1974 bronco, 100% stock. Lost track of where this vacuum line goes.

One hose goes to the original air cleaner if your lucky enough to have the OE air cleaner. '74s came with different emissions equipment depending on where it was sold. So it could have 2 hoses to the C4 vacuum modulator, an anti backfire valve in the air injection, a retard in the vacuum advance on the distributor, and an EGR valve. In other words it's complicated.

I have a home for all of my other vacuum hoses. It is an auto and I do have the original air cleaner. I guess that’s as good a place as any to start
