Wires throught fire wall
No, it's not an "ignition wire."
If you read carefully what I posted, and look at the MAD diagram, the fuse link kills ALL power to the interior of the car.
One way around this is to just feed wires through the Bulkhead connector after you remove the old terminals, and ream out the two holes or so for the larger wires.
I "sort of" did this on my 67. I bought a "almost new" Painless?? wire harness that someone started to wire, some of the dash cluster wires were cut short. Mounted the fuse panel on the firewall right to the left of the heater and above the throttle pedal, and ran the wiring through the bulkhead connector as described.
I also converted my ammeter to a voltmeter as in this thread (not my invention)

and I used a relay box out of a junker Caravan? Voyager? which I mounted under the hood, and then had relays for ignition/ headlights/ pump/ security/ etc and extra fuses for same
