Hey there,

Does anyone know where I can locate a vacuum hose diagram for the underdash/heater case? Seems that in my quest for putting in the new underdash wiring, I have found that none of the vacuum hoses were hooked up. And being sort of a "novice" in this, I have no idea where to start or where they go.

Any help would be greatly appreciated.

Thanks in advance,

Check a Pro Products wiring diagram, available at any Mustang shop for about $10. They list all wiring and vaccum hoses with illustrated pictures. I have one for my '66 and my '69 ... best $20 I ever spent.

I believe I got my vacuum and wiring booklet from Mustangs Plus in Stockton. It's put out by Pro Products and is fairly detailed.
