When I have converted older trucks to 12-Volts, I have used a solid-state 3-terminal voltage regulator to power the gauges.

On GM's, some type of regulator or resistor setup is a MUST ahead of the gauges, to drop the voltage, and I'm sure using it on the Fords makes like a lot easier in the IVR (Instrument Voltage Regulator), since it will now be fed the voltage it was designed for, rather than about 14-Volts.

A common regulator is the 7806.

Here's a circuit I use:

I was searching the 'net for a similar diagram, and found the FORD page linked below.

They show you nearly the same circuit, lacking the diode I use to get the extra .7 Volts, so that apparently works, too. These circuits are limited to about 1 Amp, which will easily power the gauges, and on the linked site are also diagrams for circuits to output MORE current, if needed.
