The Breakout Box J1850 for Harley Davidson specifically makes the motoscope pro compatible with TwinCam models equipped with the older digital bus (SAE J1850).

Select your model and you will receive the bus adapter and the correct connector for your vehicle. This connector only has to be connected to the screw terminals of the breakout box. The connecting cables of the motoscope pro are also connected to the breakout box. Then the connector is plugged to the original wiring harness and the motoscope pro is working. It could hardly be simpler.

This Breakout Box J1850 is suitable for all H-D with TwinCam engine from 2004, plugs from DEUTSCH and dashboard on the tank (TwinCam). Also suitable for all H-D Sportster from 2004 with plugs from DEUTSCH (XL DEUTSCH) and all H-D Sportster from 2004 with plugs from MOLEX (XL MOLEX).
Furthermore suitable for all H-D Vrod with plugs from DEUTSCH (VRSC)

This breakout box J1850 is not suitable for models with the new bus 'H-D LAN'. Also you can not connect our other instruments here. Use the m-CAN J1850 for this purpose.
