Siren
Install the siren in the engine compartment, exposed as little as possible to spray water and
heat from exhaust or turbocharger components (minimum distance 30 cm). The Siren aperture
must face downwards to prevent water accumulating in it.
The Siren must not be accessible from the underside of the car.
Pull the Red, Blk and Blu wires through the rewall and connect the wire to the enclosed con-
nector housing as follows:
Connect the wire to the LIN bus connector (P6 or P7) on the alarm unit. Do not use a LIN bus
splitter to the siren.
Leave the Blk/Gry wire in the engine compartment for connection of the hood switch.
Important: Never install the Siren with the aperture facing upwards.
