Wiring help for trunk mount battery

A ford solenoid is not designed to stay energized for long periods of time.
When referencing the diagram at the top of this thread, if using a one wire alternator in a drag car that has no factory wiring, where does the alternator output wire come into play? Also, I'm using an MSD7AL-2 ignition, would the +12V 'ignition exciter' wire, from the ignition toggle switch on my switch panel, take the place of the 'field' wire going to the CDR in order to kill the ignition when the kill switch is thrown?
