I have one - doesnt really give you that (more) much info over what the gauges already provide.
It connects to the diag port next to the drivers seat.

The gauge came with a long enough cable such that i was able to plug it in to the port & then hide the cable under the carpet and behind the dash (i hate having cables dangling or showing).

I don't have a picture of it on my dash - i'll get one tomorrow & post it before i head out to CoTA Tomorrow afternoon.
