2023 Ford Bronco, Perimeter Security Module Wiring?

I have the full size Ford Bronco with Ford's Perimeter Security Security System installed (Part# ML3Z19A361A). I would like to request any help with two objectives I have below.

Primary Objective: Add a motion sensor to the existing Ford security system such that it senses motion inside the vehicle when I have the top off.
     I plan to use Directed Electronics 508D, Dual Zone Motion Sensor for this unless another there is a better recommendation.
        Question:   Can anyone provide the wiring description for each of the wires on the Ford Perimeter Security System?
     I suspect/hope it will have the arm/disarm, warn, alarm trigger wires I need for the motion sensor.
        Question:   Any other Bronco wiring information, location, suggestions that might be helpful for this.

Secondary Objective: Make the Ford Perimeter Security module trigger an added siren instead of the horn.
        Question:   Does anyone have any wiring insight for the horn circuit and/or recommendation for accomplishing this?

Thanks in advance,
-Jeff
