Parts Question - Parking Brake Actuator

Folks, I am rebuilding a "lightly totaled" 2018 Trailhawk. The Rear Left suspension is being fully replaced. the one item I have not been able to successfully source is the cable for the parking brake actuator. I can't find a part number in any of the parts diagrams at the typical Mopar parts houses. The dealer has not been much help. They keep telling me its a Antilock Brake Sensor, which is 68273185AA or its replacement 68372700AA... I already have the ABS sensor/cable.

I have attached a photo of the actuator and the connector point.

Thank you to anyone that can help me save time digging for the part number!
