My stock '68 289 2bbl coupe has a dual vacuum advance with two vacuum ports (one on the front and one on the side). It also has a Thermo-Vacuum switch on the thermostat housing. I am unsure how to route the vacuum hoses to these devices from the intake or carb. That's assuming that the Thermo device is used for the vacuum advance. Any help?

I scanned in some diagrams for you. They came from the Chilton "Ford Mustang/Couger 1964 - 1973 Repair Manual". You may want to aquire one of these books, they are worth it.

You can find the diagrams here.

Thanks so much, you gave me exactly what I need. I have an old chiltons which does not have these so I assumed the newer ones would not either. I will have to get one now.
