This diagram based on the '73 B-body 60-amp wiring shows one way the factory wired to reduce the load on the mulitconnector.
It is very similar to what the factory planned for 67-9 a-bodies - although I'm not aware of any evidence that any 67-9 a-bodies were actually wired this way.

In this arrangement, the stream of current for recharging the battery is split off at the terminal block.

It would also work just as well if the original R6A was left in place.

In fact on some '73 up A-bodies with rear window defroster grids, the ammeter post had multiple ring terminals on it.
