Brown Wire - (Negative Siren/Horn Output):  

The Brown wire is a 1 Amp

Negative output designed to operate an electronic siren or the vehicle's existing horn relay,
which in turn will sound the horn for audible confirmations, and also to sound the horn
intermittently if the alarm is triggered.  The alarm is already programmed to have a steady
output to operate the electronic siren.

Sounding the vehicle's horn instead of the electronic siren would require changing Pro-

grammable Feature #18 from the preset steady output to a pulsed output to properly sound
the horn.

SIREN CONNECTION: After mounting the siren, route its Red and Black wires to the

alarm control module.  The Brown wire may be connected directly to the siren's Black wire,
and the siren's Red wire is connected to the Siren (+) Supply terminal on the module.

Mounting The Siren:  Find a location in the engine compartment away from the extreme

heat of the engine and manifold.  A suitable location will offer a firm mounting surface, will
also allow sound dispersion out of the engine compartment, and not be accessible to a thief.
The siren must be pointed downward to avoid moisture collecting inside it and to enhance
sound dispersal.

HORN CONNECTION: The Brown wire may be connected directly to the vehicle's

existing horn switch wire, which is typically found at the steering column.  The correct wire
will show Positive 12 Volts normally, and no voltage when the horn is honked.  Direct
connection of the Brown wire is to an existing horn switch-to-relay wire only.  Once the

locked or unlocked by the inside doorlock knob or
the key in the exterior doorlock cylinders. The
polarity supplied by the switch determines if
the pump sends vacuum or pressure through
hoses to the actuator. Since the pump must
operate for about 3 seconds, the doorlock
pulse must be changed (Programmable
Feature #13 must be turned off).
