Ford Shop Manual(s), by Helm, Inc., available at:
www.helminc.com ($90+),
www.books4cars.com (~$60 used),
www.ebay.com.
The Ford Shop Manual for the early years comes as a large "Taurus" book, plus a "SHO" specific complimenting manual about 3/4" thick, I believe. The later years (like my 95) comes as a 3" Shop Manual, including SHO specifics. HOWEVER - be advised that there is a companion manual (to all years, I believe) called the EVTM, electrical & vacuum troubleshooting manual, which has all of the detailed diagrams for the cars. You will find MANY occurances in the Shop manual where it says "See EVTM". I have both for my 95, a Chilton's (Autozone), and a Haynes computer codes book.
