Not at all surprised. They say that the version with wires hanging out exist but I've worked on lots of lean burn equipped vehicles and have only had 1 with the wired up carb, that was an 84, 5th Ave,
There was a point in the 80s where many cars got the wired up version but not trucks, otherwise I think it was a California type thing.
What you WILL find though is that a lean burn carb won't have the vacuum port that's needed for a vacuum advance pod so a different carb is needed for that.
