bulkhead Ammeter connectors

I can be persuaded when it comes to safety..
So say hypothetically if I leave the amp gauge in place and bolt the ammeter connectors together and insulate good and tie up under dash.. then install a temporary volt gauge under dash . Then I could always bring back to original if I please or sell car..
Would this eliminate your concerns? ( I realize I will still have the bulkhead connector issue..)
Also I bypassed my "in fuel gauge" limiter and am using a RTE solid state limiter .. (picture) thanks RedFish

I can't say what is best for you and your car. Its a personal preference thing. I refused to have a dead gauge in my inst' panel and another gauge in another location to look at. Once the screen and needle from the amp gauge are transplanted onto the Sunpro volts gauge there is no difference in outward appearance except that when the switch is turned off the volt gauge needle goes home (just like the other gauges). The switched 12 volt supply that you routed to the solid state regulator is used to supply the volt gauge pos' also (where the circuit board is marked RED). And a ground wire added to neg' post of volt gauge. Another amp gauge would be required to put it back to OEM.
