Coldweather kit controller

Does anybody know where a person might find one of these controllers?
The heater on the 8x8 runs on diesel and requires extra controls...

I think that looks like the one in my shopvan. They use a fuel fired heater too.

Possible, this one is probably only mounted differently. I goes on the top rail of the wind shield.
The controller itself is all I'm looking for, the section (box) to the right on the mount.
