This simplified diagram is from the MAD electrical article on the ammeter/ bulkhead connector. It applies to "most" old Mopars

The path for coil current is not fully shown above. Ignoring electron flow, the "path" is battery---fuse link--through the bulkhead (BIG RED) to and through the ammeter, out on BLACK---to the WELDED SPLICE and branch off at the splice to the IGNITION SWITCH and from there out of the switch on the (brown?) IGN2---back out through the bulkhead connector and to the coil + side of the coil
