This cable has been designed to interface with KEY820's that have the capability of programming 2018+ Chrysler vehicles. It functions by intercepting your programmer's CAN high and low signals and passing them through 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.
How to use:
1) Plug the main cable of your IKEY820 into the female OBD port of the adapter.
2) Locate the star module on the vehicle. Location varies from model to model.
3) Locate the plastic green strip with white cables plugged into it. Probe your red (CAN HI) into the green cable of the first plugin, and the black (CAN LO) into the yellow wire.
4) Use your programmer to select by vehicle or system type and program like normal.
