When I borrowed one for a few days, I mounted it kinda countersunk, in that panel between the steering wheel and the gauges, and off to the right a little bit. So I could still see the speedo completely, and it just barely blocked my gauge gas slightly, that's all. If I ever buy a Dashhawk (not hesitating on one, just not sure if it's worth buying one now with zero support service anymore from a knowledgeable tech team, or wait for MSD's new fancy one to come out), I'll probably put it there again, then hide the wire behind the dash and have the wire just stick out near the OBDII port, instead of running the wire outside of the dash to the OBDII port.
