do i need to use voltage reducers for my oil and temp dash gauges , after converting over to 12 volts??

thanks

Yes you do. Amps and fuel are OK. If you use "Runtz", you're supposed to use one for each gauge.

Do what Ford did, they used 6 volt gauges up to 1985 (excepting 1956) and used an instrument voltage regulator to drop the voltage to 6 volts pulsed. Napa carries the IVRs and the one for a '59 Ford uses spade terminals for easy installation. one IVR for all the gauges and the ammeter doesn't use any. I have done this many many times over the years even swapping later gauges in place of the original by swapping face plates and needles and wiring everything in the factory style IVR. Simple and reliable.

Early 70s is when the Ford gauge regulator changed from the slide-on connectors to a snap button type connector like is used on 9V batteries so as to connect easier to the printed circuit. Never seen one fail and a whole lot cheaper than the aftermarket gizmos. ..B.
