I received my new (to me) ScanGauge II this week and installed it today. It was a pretty good fit on the left side of the dash, under the AC vent.
The ScanGauge supports a bunch of different display colors so I was able to get a good match to the orange on the center console of the FJ Cruiser.
I wanted a clean look, so I routed the connector cable underneath the ScanGauge in between two pieces of industrial velcro.
To get the cable down to the OBDII connector beneath the steering wheel, I drilled a 1/2" hole in the side of the silver trim piece and routed it through. The connector, which is similar to a CAT5 Ethernet connector, barely fit through the hole.
All told, the installation was about 25 minutes and I think turned out pretty well.
The ScanGauge is clearly visible to me while driving but can't really be seen by someone driving alongside the FJ in a car.
