I was looking at my parts bin wondering where all the vacuum hoses attach, this is just what I needed and at the proper time. Thanks

What about vacuum hose schematics? I have Pro Products, Inc. '71 Mustang wiring diagram booklet that includes the vacuum diagram for the entire vehicle, but my car seems to have an additional vacuum line passing through the firewall. There's 2 vacuum lines that are routed through the firewall near the centerline of the car via the same sealing grommet. Then there's the single vacuum line that I found towards the passenger side, about 6" from the aforementioned grommet. No idea what this is for, but I've got it plugged for the moment.

What you described (two hoses in a single grommet) is connected to the heater/AC controls to operate the various vacuum motors. Chuck

I can't find a single vacuum hose entering the passenger side of the firewall in any reference I have. I suspect that a previous owner had added some aftermarket device, like a water injection system.
