OK, let's go to basics:-
Is your alarm controlled by buttons on the factory key or is there a separate remote control fob?
If separate is there an FCC number on the back or a name.
PS Have you confirmed that there's a factory alarm on board?
With apologies to Kreg.

Then you first contact a Chrysler dealer and see what they say.
One doesn't mess with factory alarms without a circuit diagram.
If there's a factory LED you might be able to parallel wire others into the circuit but you'd need to know the supply voltages, usually around 2.5VDC.
Frankly not a job I'd bother with on a modern car.

You could buy and install one of those two wire pseudo alarm blinking LED's or strobe strips off EBay for $5.
Easy install and it would start blinking whenever the key was in the OFF position, regardless of the Factory Alarm being set or not. ------------- Soldering is fun!

Wire the red to a constant 12V+ the black to ignition.

No it would be wired completely differently as above you could only use it for one or the other purpose.
