Bus lines can be reached with Back Probe Pins at screw
terminals at a device’s wire entry point: wire colors
commonly used are white for CAN_H, blue for CAN_L,
and black for CAN_GND.
Alternatively you can use a third party DB-9 to 4 mm
banana breakout box. In addition the figure below shows
the pinning of a DB-9 female connector and a typical
Automotive (OBD2) connector. Bear in mind that some
automobile manufacturers leave bus signals at the
connector default on, other manufacturers require bus
signals to be enabled via an external controller.
