ScanGauge E - Mounting Location
I picked up a cheap, used ScanGauge E on eBay and had been trying to decide where to mount it. I went through several options: above the gauge cluster (long ugly wire run), underneath the AC/heat controls (too low to see, might bump it when shifting).
I finally decided that on top of the left hand air vent would be the best. I was concerned that because of the curve, such a small contact area of Velcro might not be sturdy enough, but it seems to be plenty sturdy. It's easy to see without having to take my eyes off the road, and there's only the short bit of cable running out of the back. The cable runs behind the rubber trim covering, excess wire coils by the hood release, and in it plugs. I might look into removing the panel that covers the electrical connections and seeing if I can safely route the cable completely behind the dash.
