There is no direct plug in for the shock sensor on the EVO-ALL.
The RFA2A is only for an RF-KIT.
Once option G is enabled, and only when option G is enabled, both trigger wires of the shock sensor need to be connected to the PURPLE wire of the 20pin connector. The purple wire is a dual stage shock sensor input when option G is on. When option G is NOT on, it is a unlock input.
If you want to use the EVO-ALARM feature on the evo-all, please follow this guide for guidance on what the inputs/outputs will be once the EVO-ALARM option G is enabled. https://cdn02.fortin.ca/download/16221/16221.pdf
