Simplify the installation of your electronic speedometer with this new GPS Speedometer Sending Unit from Speedway Motors.
This is the latest technology in sending units for electronic speedometers. Speedway’s sealed electronic sending unit uses GPS triangulation to calculate true ground speed regardless of gear ratio, tire size or any other mechanical factors. No calibration is needed! The GPS Speedometer Sending Unit has a very simple four-wire hookup and can be used with 8- or 16-pulse aftermarket electronic speedometers. The compact unit has a footprint about the size of a business card and can be mounted under the dash or under the hood, requiring only 3-inches of clearance between the top of the unit and surrounding steel.
