Ford Perimeter Plus Vehicle Security System

[linsys]

I see on Ford's website for my 2020 Explorer ST there is a "Ford Perimeter Plus Vehicle Security System" (Part: KN1Z19A361A). Is there a way to tell if this is already installed?

Here are the instructions for it. Good chance it's not installed.

Unlock all the doors, get in the truck, lock the doors with the fob, and move around inside the truck. If the alarm goes off then you have perimeter sensing.
