Nope. Simply make up a plug which connects the large brown wire to the
Alternator connection. The smaller brown wire is blanked off. As for the
alternator warning light, see below.
3) You lose the function of the alternator warning light. The one-wire

I did. On the plug made above, the warning light wire is connected into
the left spade connector on the Delco alternator.
As a caveat, I did not spend the big bucks to get one of the "Street Rod"
alternators from the local parts house. Being a bit of a cheapskate, I
went to a local starter/alternator shop and he, being very helpful when I
explained what I wanted, took a basic off-the-shelf Delco alternator of
65 amps, removed the back and installed what he described as a "self
energizing regulator". Took him all of 5 minutes. This alternator has the
provision for a alternator warning light as stated above.
Not all "single wire" alternators are created equal
