Everyone, I have discovered the problem. After reviewing my Haynes Manual wiring diagram and checking wiring circuits, turn signal switch, hazard switch, it turns out the the manual location for the turn signal flasher was incorrect.
The turn signal flasher was supposed to be on the fuse panel. Seems logical, but it turns out that this was the hazzard flasher. The turn signal flasher was behind the radio, which the manual said was the hazzard flasher and supposed to be above the glove box.
My visiting sister in-law has a 1988 Mustang. Her turn signal flasher is located behind the fuse panel, by itself on an idependent wire connector. Seems the factory workers put it wherever they please!
Hope this helps someone else.
