I'm right handed and would prefer the switch panel on the right hand side. Also would put the gauges across the top with the tach on the left as you would read,(left to right) the tach being most looked at, plus would it occupy the space better in the space over the bottom machine. Then water pressure, temp, volts, and finally hour meter. Just my two pennies, not trying to totally pick apart your set up. Good pics on your photobucket!
