Coach Controls Wiring Harness?

One more question for you! They list the height of the box as 2.5". I'm guessing that is just the can. How tall would you say the main body is?

The height to to top of the knurled bolts that hold the cover on is about 2 3/16" The height to the top of the cover is about 1 7/8" . Kind of a bad angle, but you get the gist. It's nowhere near 2.5"
