I'm trying to wire up a cellularly connected microcontroller to remotely control the locks on a 2017 Nissan titan.
I have located the wires that I believe are involved in triggering lock/unlock. However, I'm not exactly sure what is happening so I'm not able to simulate lock/unlock being pressed with the microcontroller.
Here are some annotated images from the passengers side door.

Any information about how the locks are controlled would be appreciated.
If there is any information missing let me know.

On the 2017 Titan you'd use the analog alarm arm and disarm wires to control the locks. In the Driver's door at the power window switch, the white/red will pulse negative when you use the key in the door to the lock position, the black/white will show negative when turning the key to unlock. The unlock requires a double pulse to unlock all doors.
