89 Helms diagrams , which one to get.

[Phoenix]

To get the 89 electrical diagrams I need to get the SHO supplement , or the regular taurus EVTM book?

You need the EVTM book. It has all the electrical and vacuum for all Taurus/Sable models. The SHO supplement is generally mechanical with a little electrical stuff like alternator wiring in it.
