Classic Instruments is pleased to announce a revolutionary speed signal interface, the SN74Z. The SN74Z, is the perfect complement to your Classic Instruments speedometer or tachometer. It has the ability to function as either a speedometer or tachometer interface and it works with many standard aftermarket gauges. The SN74Z installs in line between the signal source and the instrument. It features an LED display and integrated push button to aid in calibration. It measures just 3 inches wide by 2 inches high by 1.5 inches deep and has mounting holes for easy installation under the dash. A convenient wire terminal strip ensures easy connectivity for electrical connections.
