The Speedhut GPS Speedometer brings modern precision to your vintage Datsun—without the hassle of traditional speed sensor wiring. Powered by a high-performance GPS module, it provides real-time speed tracking anywhere in the world, with no need for calibration, gear ratio setup, or transmission hookups.
Installation is simple: just connect 12V power and mount the included waterproof GPS antenna. With a 3-wire hookup and no drivetrain connection required, it’s an ideal solution for Datsun restomods, engine-swapped builds, or anything running a non-original transmission.
With stepper-motor needle movement, LED backlighting, and rugged construction, this speedometer delivers the accuracy and reliability your Datsun deserves—whether you're carving canyon roads, daily driving, or hitting the track.
