It functions by intercepting your programmer's CAN high and low signals and passing them though the attached probes. Depending on your plan of attack, you can tap the CAN wires directly in the STAR module, in the vehicle instrument cluster or at the wires which transport the information between the STAR module and the immobilizer. The OBD throughput will feed 12V back to your programmer to keep it charged if that feature is supported by your machine. The Chrysler/Dodge/Jeep 2018+ Universal Programming Cable has been certified by Lock Labs for the AutoProPAD and AutoProPAD LITE models.
