'64 dart amp gage

Before you do that, check if your car is one of the years that has the BIG terminals for the ammeter pass through. I can never remember..............

Below is the engine bay connector for a '65 (I don't have a 64 manual) See the two big center terminals? You have those?

YES, the 63 dart is like the 65. I actually have a 63, 64, 65 darts. funny how the 64 firewall is the later type where the black and red hot wires go in to the plug that plugs into the firewall. weird!
