Will these gauges work

[69Ford]

I would like to know if these gauges will work with my electrical system. They are early 60's big truck gauges and I want to put them in my 69 F500 cluster
do the early 60's gauges have different voltage requirements. Any info would be great thanks

They will work just fine. All Ford guages use the same voltage, that is why later ones have ivr's, Ford did that so when they went to 12v they did not have to change anything. They also found out that the guages were more accurate and stable with an ivr so they never changed until they went digital. Having said this, be sure to use one if the cluster doesn't have one although I think that one is late enough to have one. Hawkrod

Thanks Hawkrod I'm still looking for a set of these gauges.
