Electrical Passanger Door Lock Actuator Won't Work. (89GT)

[1989MustangGT]

Hi,
I'm dealing with an issue where ONLY the passenger auto door lock will not work. The driver side window and door lock work fine. The passenger window works fine.

The door lock actuator is new and I've tested with a battery that it works. The wiring harness is mostly new. All the wires are feeding power to the plastic block and switch. The actual switch has also been exchanged. The wires that lead to the switch include a Pink/Black and a Pink/Orange.

Does anyone have any idea why only the passenger lock actuator will not engage/spin?
