I went in search of such a thing and most of what shows up is installation/setup for jaguar/jazzmaster guitars, which are essentially the same thing. The Mustang was more of a "student" or child's guitar, so there aren't as many out there. In all cases, the procedure is basically the same. Use the post height adjusters to get it close, then use the individual saddle height adjusters to match your fretboard radius. It's pretty straightforward.
