i just pop the scangauge in the windshield driver side. Fit there perfectly!
Its a shame I can't view average mpg and mpg instant at the same time ( you need to press a few buttons to view trip (average mpg) or gauges (Instant mpg, and 3 other views) but at least I won't be as distracted. Although the scanguage is right in my view, I tend to give too much attention to it and I think I got enough to deal with.
At least it works like a charm, one of the best FE mods I ever bought.
If your reading this, then good for you, your saving some gas because your here.
