That is what I've seen as well. If you look at the two tabs for the connector that stick through the alternator housing, some one-wire units actually have these two tabs connected by a little metal bridge strap. Obviously, this won't work as a three wire unit. I have never seen an OEM one-wire unit, though some marine applications may be set up that way.
