Fuse Box Repair?

I bought a painless 7 circuit box, modern fuses, comes with wire.
Iirc, 3 constant power circuits, 4 ignition power.
Fuse box fit in the stock location.

Incorporated it into my existing harness using factory correct Packard connectors and the stock plastic connectors.
Ran 1 wire to the ignition, 1 to headlight switch, 1 for radio, 1 for heater, etc.
More than enough circuits.
