Product Description

Dakota Digital Aftermarket Speedometer/Tachometer Interface For Harley J1850 Motorcycles

The Speedo/Tach interface from Dakota Digital allows you to interface Dakota Digital and most aftermarket speedometers and tachometers with the databus signal created from the stock Harley-Davidson ECU, with the exception of some Softail and Dyna models.

Features:

  • Allows simple installation of an aftermarket speedometer and/or tachometer
  • Plugs directly into motorcycle's diagnostic port
  • Connects to bike's data bus and outputs traditional analog signals
  • Features outputs for speedometer signal (8000 ppm), tachometer signal (adjustable for 1-, 2- or 4-cylinder), check engine signal, accessory power and ground
  • Digital readout works like a scan tool; allows reading back and clearing diagnostic codes

This device connects to the bike’s data port and outputs traditional analog signals for a gauge of your choice. Outputs provided for accessory power and ground, tachometer signal, and speedometer signal.

In addition to wired outputs, the Speedometer/Tachometer Module contains a digital readout which allows for both reading back and clearing diagnostic trouble codes, similar to a scan tool!
