Part Description
Break-Out Box for J-1850 Databus, not suitable for CAN-Bus equipped models
Text excerpt from the catalog:
This Speedometer/Tachometer Interface Adapter is also known as the Databus Break-Out Box. It allows you to interface most aftermarket Speedometers and/or tachometers with the SAE J-1850 Databus signal created from the stock Harley-Davidson ECU on 2004 to present 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, adjustable tachometer signal for 1, 2 or 4 cylinder outputs (which includes V-Twin Single Fire and Dual Fire applications), speedometer signal (8,000ppm only) in addition to the Check Engine signal, normally only available on the data bus. The Break-Out Box also contains a digital readout which allows for both reading back and clearing diagnostic trouble codes, similar to a scan tool. Kit comes complete with required harnesses and hardware. Note: Does not work on 2011 and later Softail and 2012-2017 Dyna as these have a so-called CAN-Bus system.
