Classic Instruments has launched the CI Drive speedometer interface, designed to operate a cable-driven mechanical speedometer using an electric speed signal from GPS or a vehicle speed sensor (VSS). The standard SN85 kit includes a common cable for GM, Ford, and Mopar applications, with separate purchasing options available for less common applications.
The CI Drive features easy plug-and-play connections for a simple installation, which can be done in the dash or under the hood, although it is not waterproof. Assembled with high-quality components, the interface allows customers to maintain the original mechanical speedometer style.
The standard GM/Ford/Mopar cable has a drive output thread of 7/8″-18 and a square of 0.112″. The calibration range is from 170 to 1650 turns-per-mile, with a default calibration set for U.S. speedometers at 1000 turns-per-mile; the unit automatically calibrates when using a GPS signal through the included GPS antenna.
The new CI Drive speedometer interface can be purchased directly from Classic Instruments or through authorized dealers and on holley.com.
