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

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. 

That's why i'm having problem with door lock and unlock with G option ON?

as RFk912 is not locking or unlocking with G option on?!!

It's actually purple/white the shock sensor input not purple.

I dont why  you are having lock-unlock not working.

Purple and puple/hite are inputs, not outputs. They simply change purpose when G is On.


On GM, Door locks are controlled on can-bus or through analog outputs if programmed without onstar.
i connected red wire to +ve , Black Wire connected to GND, blue wire has been connected to purple/white wire

armed the car and tried moving the shock sensor, horn alarm not firing, only red color led inside the shock sensor is illuminating upon movement but alarm is not firing, tried to increase and decrease the sensitivity, nothing changed

what it could be now?
Did you connect the horn?

The green wire is a (-)horn output. It needs to be connected to the cars (-)horn trigger.
yes connected and horn chrips already with lock and unlock
