I've had overheated connections at the firewall connectors and at the headlight switch on 2 Cuda's. Other Mopar owners have had the same thing, including fires. I don't want any fire risk after doing this restoration!!! I've bypassed the ammeter (converted to a voltmeter) and connected the 8 Ga wire direct to the starter relay. This prevents battery charging amps from flowing through the bulkhead connector.
A side benefit is far brighter headlights.
