Possible Scangauge alternative? (round vent gauge)

[Diemaster]

I was looking for something else related and found this. It says it fits the round vents in newer mustangs. I thought "well my Class C has round vents and is from Ford. Perhaps 2 universes under one God could collide. (not calling Ford God; there far from it. Toyota maybe...)

I dont see any mention of MPG but it does have analog inputs, something the scangauge does not so you could get a boost/vacuum gauge or something.

At almost $400 it's a mighty expensive alternative.
