Well if this mini gauge is electronic, there has to be a pickup mounted somewhere around the motor, transmission or some rotating mass. And even if you find a suitable/feasable/doable locale for the pickup, how's ya gonna calibrate it? Thar's usually dip switches on the back, but they hafta be flipped in a sequence for a myriad of applications and ratios. Sounds like a whole bunch of trouble for a small return to me, but that's just my ramblin'.
P.S. what be wong wit the gauge we has now? people may laff and point and say you have a pin head speedometer, so you should keep the one you have and buy a tool bag and some other stuff instead.
