This might be a tough one. You will definitely need that meter and the schematic from the CD.
F9 feeds the PCM power relay in the underhood panel. The output goes to the VSS, the EVR solenoid, the PCM, EVAP valve, the CP solenoid, the MAF, the IAC valve, the ATX (supply for all solenoids), IMRC module, and the AC WOT relay.
Locate the load side of the PCM relay, and verify that the short to ground still exists. Then, unplug each device, one at a time, and see if the short circuit goes away.
If you're lucky, one of the load devices will be the fault and, once disconnected, will remove the short circuit.
If you're not lucky, you'll have everything disconnected and the short will still remain. If so, you'll have to locate each of the relevent splices, undo each, and see which leg has the short.
The EVTM diagram is not for the faint-of heart. It is, IM(Not So)HO, the worst diagraming format that Ford ever used for it's schematics and was only used for a model or two, including the Contour and Cougar.
If you get stuck, let us know.
