bulkhead Ammeter connectors

Darren, I did the Mad bypass. It's a personal choice. I left the ammeter(unhooked) in dash as I like the original looks. But dont trust 50+ year old gauges. We installed a triple gauge set of Autometer gauges(volt, temp, oil psi) directly under the ac diffuser.
The #1 priority in my opinion are cleaning the connections and upgrading the wiring.
