Go to the top of the page and click on the 7173Wiki. Scroll down a little and you will find the schematics for our cars. Also, welcome from Ohio. As it looks like you're a new member here, please post some pics of your car and give us a little bit of background info on it.

I found on Amazon a very good wiring and vacuum diagram download to Kindle, "1973 colorized Mustangs Wiring Diagrams Kindle Interactive Edition" $12.95. The only diagram I have found that shows the correct vacuum for a 73 under the hood and AC-Heater.

I like the colorized 73 Mustang schenatics from forel Publishing. There are a few very minor errors I have annotated, and I added some other info I felt was helpful for my needs. Below is their web site. They have PDF files for quite a few First Generation Mustangs/Cougars.

If you need engine vacuum hose schematics they do a great job of covering that beginning in their 1973 Shop Manual, Volume VI. The only vacuum calibrations they left out are from 1973 351C 4v carburetor engines. I have the calibrations for those 2 missing schematics, attached to this post.

For Mustangs and Cougars 1967 - 1972, Mustang Barn pulled together a really solid group of calibrations. With the knowledge and permission I assembled all of their calibrations into a single PDF file grouped by year, and sorted engine size. Fee; free to shar the PDF file as you see fit.
