There are a couple of, what look like, alarm Sonar sensors up in the headlining, either side of the Auxiliary Lamp unit. Facing backwards into the interior.
Are these standard fitment on the Crossfire, as part of the factory alarm system, or not?

Aside from the Chrysler Keyfob (plus Spare) I have no other keyfobs (that might indicate an aftermarket alarm is installed). Plus wondering what these were.
