No spark when cranking

This is a bit misleading, because it is not per se in the ignition circuit. It's in the CRANKING circuit. This is easy to fix. Just look under the hood for the manual reset, about the size of a horn relay. There are two yellowish wires, one yellow black. You just wire those permanently together

This device originally breaks the wire to the starter relay

So how come my Charger would crank all day but never fire if you didn't buckle the belt after sitting down but before you turned the key? Think maybe B bodies were different? I know the control box was not like the ones pictured and was mounted on the firewall between the heater fan motor and the cowl/fender brace. Now ya got me curious...
