Had a request today for the vacuum line the vacuum line routing for a 69 Mustang so I thought I would post the scan here for everyone's usage. I also placed this scan and three others (with AC/Heater operational diagnosis chart) in an article in the library. Scans are from the 1969 Wiring and Vacuum Diagrams service training course. Hope this helps others
