I'd never noticed that what I call a thermostat housing, or goose neck, is a "connector" in Ford speak.
And, I can't tell you what this one fits as I can't find E0TZ 8592-D nor RH-12 in the catalog. I'm not saying that this isn't the right part for a Bullnose. In fact, with the E0TZ I'll bet it is. But it looks like this one was superseded and removed from the catalog.
