Harley-Davidson Aftermarket Speedometer / Tachometer Interface
From Dakota Digital
The STM-100 allows you to interface Dakota Digital and most aftermarket Speedometers and/ or Tachometers with the Databus signal created from the stock Harley- Davidson ECU 2004 up (excluding 2011 and newer Softail models and 2012 and newer Dyna models, 2014 and newer Road King).
This device connects to the bike’s databus and outputs traditional analog signals for a gauge of your choice. Outputs provided for accessory power and ground, tachometer signal (adjustable for 1, 2 or 4 cylinder outputs), speedometer signal (8,000ppm)** in addition to the Check Engine signal, normally only available on the data bus.
In addition to wired outputs, the STM-100 contains a digital readout which allows for both reading back and clearing diagnostic trouble codes, similar to a scan tool!
**The STM-100 will only create a 8,000ppm signal, please validate that your aftermarket speedometer is user adjustable before ordering.
