Note: The Driver Pin Switch Often Will Have An Extra Wire That Goes To The Ignition Key Warning Chime. This Circuit Will Trigger The Security System,
But Only From The Driver's Door, And Is The Incorrect Trigger Wire. Please note that Positive Courtesy Light Pin Switches Will Have One Wire Which Will
Remain (+) 12 Volts At All Times. At Least One Other Wire Will Have (+) 12 Volts When A Door Is Open, And No Voltage When All The Doors Are Closed.
This Type Of Switch Will Operate The Dome Light Even If Removed From The Chassis Of The Vehicle.
Negative Siren/Horn Output
Brown Wire
The Brown wire is a 1 Amp Negative output to operate the system's audible functions. This output is programmable, and may used to sound an electronic
siren (program "steady", the factory setting) or the vehicle's existing horn (program "pulsed"). Instead of the siren, if the vehicle's horn is preferred, this
output must be changed from steady to pulsed, allowing the use of the horn for the alarm's audible responses. If the vehicle does not utilize an existing horn
relay, one must be added or the output's 1 Amp capacity may be exceeded, which will damage the control module. The electronic siren requires a continuous,
steady output. The siren features six different siren tones, which change every 5 seconds. When configured for use with a horn, this output pulses for 10
seconds, then pauses for 5 seconds, repeating this cycle for the duration of the activated alarm period. This prevents the horn from overheating, thereby
ensuring a maximum useful horn life to the vehicle owner. When this output is programmed for pulsed horn operation, an additional programmable feature
allows loud or soft confirmation honks.
CONNECTION: If used with the electronic siren, the Brown wire may be connected directly to the siren's Black wire, and the siren's Red wire is
connected to the Siren Positive Terminal on the system's control module. If used to sound the horn, 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 vehicle's horn wire is identified, probe the
wire with a standard test light connected to Negative chassis ground. If the horn honks when probed, a direct connection may be made. If not, use the
following diagram to configure an optional relay. CAUTION! This is one of the few uses left for a standard test light in a modern vehicle! Use a digital
multimeter (DMM) to identify the horn wire first. Probing an Airbag circuit with a standard test light can cause the Airbag to deploy!
AU-72 Electronic Siren: The AU-72 Electronic Siren has a 127 dB (decibel) sound level and features six
police siren sounds which change every 5 seconds to produce twelve sounds per minute. These sounds may be
programmed (described below) to customize the audible output of the alarm. The AU-72 also features softer
confirmation chirps, which may be changed to full volume by cutting the Black loop wire on the siren. This
siren's sound output is 127 decibels (dB) and rated at 12 Volts, 2 amps. The AU-72 measures 3 7/8" round and
4 1/8" deep and has twin 12' wiring leads
