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
