There is a small, but faithful following of SG (I & II) users on the site. Do a search and you'll probably find several thread with comments and users.
Mine is mounted is a similar position to 'CrazyJ' (picture below for crazyJ's setup), but mine is seated back in futher so it does not 'tilt' out. I ran the cable through a small hole in the removable panel in the cubby. No cable mess that way.
I typically have the following up:
MPG
Gallons/Hour
Water Temp
Voltage
You can read about some of the crazy MPG figures dedicated Si (and other) drivers have gotten by being mind controlled by their SGII
