Turn Your Mechanical Drive Speedo Cable with an Electronic Speed Signal with Classic Instruments
What do you do when you want to retain your original cable driven speedometer, but plan to upgrade to a modern electronic overdrive transmission that only has an electronic output signal? You call Classic Instruments for one of their new CI Drive Speedometer Interface kits!
The new CI Drive Speedometer Interface is designed to operate a cable-driven mechanical speedometer by converting the input signal of from a GPS or Vehicle Speed Sensor (VSS). The standard SN85 kit comes complete with the common cable for GM, Ford, and Mopar applications or if you have a less common application, the box and cable can be purchased separately.
The CI Drive features easy plug and play connections and can be installed in the dash or under the hood (although it is not waterproof). The common speedometer cable that comes with the kit has a drive output thread of 7/8″-18 and a internal square size of 0.112-inch. There is also a calibration range that can be set from 170 – 1,650 turns-per-mile ensuring accuracy for even the most diverse mechanical speedometers! Default calibration is set to function with most domestic speedometers at 1,000 turns per mile. If you choose to go with the GPS input signal, the unit will automatically calibrates with the included GPS antenna.
Finally an easy way to drive your vintage mechanical speedometer from an electronic input.
