most alarm brains are in the exact same place....under the dash on the driver side...its just easier for the installer...

heres some tips....somehow after the install mask all the wires black....dont put the sticker of the brand of alarm you have on your window...if the LED has the brand name on there, cover it.

all of the above gives clues as to which alarm you have.

2 sirens is good..the traditional under the dash, and another inside the cabin. there are sirens small enough to put inside of the vents, although that made block airflow.
