The Ultragauge comes with a window mount, I wish I had a picture of mine, but anyway, I have it stuck to the windsheild over on the left, and run the cable down the side of the dash, just tucking it into the trim and plugged it into the diagnostic connector.

Mine is set to display IAT, Engine Temp, RPM, MAP and two other sensors I cant even remember!

It's not only a useful tool for when a code is set, it's really a fun and very cheap toy!
