Factory ammeter

I've built kits for factory hemi E bodies, and those guys are generally "picky" about what they put on their cars.

If you are building a 100 point show car... keep it all factory. If not, JMO, use products that improve performance in many areas that can be easily hidden. If you have a battery tray in an A body, the relays hide underneath and the wiring hides extremely easily within the OEM harness and tabs.
Thanks its not a show car I just want things to be left as original as possible for simplicity reasons lol tbh I suck at wiring and electrical and I dont want to rewire or modify anything that I dont have to hence wanting to keep the factory ammeter in working conditions. I want all my gauges to work and I want to be able to keep an eye on the charging system too. I don't want the appearance of the interior to remain factory looking so I don't want to cut any holes in my cluster for a aftermarket volt gauge.
