This unit allows nearly any electric speedometer to use free GPS signals to drive the speedometer. No more cables, no more calibration drives. If you've got an Auto Meter electronic speedometer, it's a plug and play solution. Calibration on non-Auto Meter speedometers takes about 10 seconds and doesn't require driving. The Module uses the fastest possible GPS technology for truly seamless functionality.

With the push of a button, these Classic Instruments Sky Drive GPS speedometer sensors can program your vehicle's speedometer from the convenience of your garage to read in miles per hour, kilometers per hour, or knots. They feature an omnidirectional antenna that gives you added mounting choices! They are designed to work with any Classic Instruments or other manufacturer's speedometer. The Classic Instruments Sky Drive GPS speedometer sensors include two additional wires, giving you additional features and benefits. One wire gives you an extra speed signal for cruise control, and another wire can activate a relay or light which does a variety of things, such as locking your doors or turning on a warning light at a predetermined speed.
- Uses GPS triangulation to calculate speed
- Works with all electronic speedometers
- Cruise control capability built in
- Relay trigger wire built-in for additional features such as speed timed door locks or speed indicator lights
With only two touches you can quickly and accurately program your speedometer. Classic Instruments SN74 installs in-line between the transmission pulse signal or ECM speed output and your electronic speedometer. The SN74 converts all known pulse signals, including pulse sendors that replace mechanical speedo cables on early transmissions, factory VSS (vehicle speed sensor), and the computer (ECM) output signals to 16,000 ppm or 8,000 ppm signals. It also includes an additional 8,000 ppm output signal for your cruise control. Real-time calibration feature allows total fine tuning. The filtered power source eliminates interference. This compact module works with most all aftermarket electronic speedometers and the module can be mounted anywhere inside your vehicle.
This sending unit for electronic speedometers has a .894" (7/8”) female attachment nut to attach it to the transmission or out-drive unit. This is similar to the female threaded ring on mechanical speedometer cables. Most customers will need to purchase part number 66582629, square drive tip, to attach this sender to a GM transmission.
