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 Softail Models).

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.
