What will I need to make the electric speedometer work?

If you have a hall effect sender, GPS sender or magnetic speed sensor (i.e. vehicle speed sensor) already available the speedometer should work without any additional sending units.

Any speed sender or electronic module that meets the following conditions can be used with our speedo:

  • Pulse range generated proportional to the vehicle speed
  • Signal with minimum 3V peak to peak signal - typical for 3-wire hall effect and 2 wire vehicle speed sensor outputs
  • 4000-200,000 pulses per mile (16,000 is typical).

If you currently have a mechanical speedometer (cable driven) you will need a hall effect sender. The hall effect sender connects where the cable currently comes off. The signal from the hall effect sender provides the signal for the electric speedo. We sell hall effect senders for both GM/Mopar and FORD applications.

If none of the above options will work for your application the best option is to purchase a GPS based speedo sender like the one from Intellitronix. Google "Intellitronix-S9020-GPS-Speedometer-Sender" to find places to purchase.

Late Model Vehicles with PCM/Computer

This speedometer provides an output (OUT) terminal that can be used with late model vehicle installations using the existing Vehicle Speed Sensor (VSS). In these installations, the VSS signal wire should be connected to the SIG terminal of the speedometer only. The OUT terminal should then be connected to where the VSS output was originally wired. This will provide a buffered VSS signal to the PCM/computer in the vehicle.
