Complete cable for serial diagnosis of the HARLEY-DAVIDSON brand. The cable is made up of three connectors: one 4-way (diagnosis connector for models produced until 2012), the second 6-way (diagnosis connector for models produced from 2012 onwards) and the third 2-way (power supply). ). To carry out a correct diagnosis, it is necessary to connect only one diagnosis connector to the motorcycle, based on the equipment. On the other hand, the power cable needs to be connected to the vehicle battery only if the instrument is not powered through the diagnosis socket. NOTES: the cable replaces, as a sole solution, all previously produced cables (3151/AP10, 3151/AP17, 3151/AP35, AP35/OBD).
