GEN 2 Tieing into the stock alarm system

Hey guys, anyone know how to tie a simple contact make/break switch (reeed switch) into the stock alarm?

I have done this in the past to alarm various items. It’s great for trailers. A simple connector to the trailer that shorts on the trailer. If it’s disconnected the alarm sounds.

I just need to know what wires I can tie into to do this. Door switch I’m thinking.
