The new alternator has a different 2-pin connector so I removed the terminals from each connector block with the idea of simply swapping the connectors. Unfortunately the female spade terminals from the Delica harness were a slightly different style and wouldn’t slide into the connector block for the new alternator harness, so I removed the connectors from the new harness and soldered them onto the old harness and then slid them into the new connector block. Done.
I thought about just cutting the old connector off the harness and splicing on the new harness with a pigtail, but the wire gauge on the new harness was considerably smaller than that of the Delica harness and it's usually not a good idea current-wise to splice on a reduced wire gauge so exchanging the terminals made more sense.

(Working on the electrical conversion/compatibility stuff has given me even more appreciation for Growlerbearnz's having blazed the trail for this project. I'm not sure I would have had the presence of mind to do a comparison for the circuitry on the harnesses.)
