Most simply fit an equal value resistor in series with the cutout voltage coil (On later cars between E terminal and body, with any connections to the E terminal transferred direct to body.
The unit illustrated is a combined cutout and voltage regulator. Use of the latter function is a whole longer and fraught story.
The whole 12v topic been thrashed many times including recently. It is important to limit field current. Some apparently just retard the 3rd brush and take care to keep it that way. Others add a resistance about same as the field winding to reduce any accidental excess. As there is likely hidden additional current to field, it is especially important the no load ammeter charge is kept conservatively within normal recommended limit.
