1. 8-wire connector, RED WIRE (5A fuse,

to +12VDC)

Remove the 5A fuse, and connect this wire to
constant (unswitched) source of +12VDC.
Connect directly to the vehicle’s fuse box, or
to the battery (+) terminal.

IMPORTANT FOR SAFETY, DO NOT

INCREASE THE LENGTH OF THE RED WIRE.

IMPORTANT DO NOT PLUG IN THE

FUSE UNTIL ALL OTHER CONNECTIONS

ARE MADE.

2. 8-wire connector, BLACK WIRE (to

chassis ground), fig. 1

Choose a good chassis ground location. This
is the most important point of a successful
installation. A poor ground connection will
cause the siren to continuously emit a low
siren sound whenever the alarm is armed.

Use one of the car's factory bolts to connect to
chassis ground. If none is available, scrape
paint and dirt from the metal surface, and use
a grounding lug and star washer.

3. 8-wire connector, PINK WIRE

(to siren), fig. 2

A. Mount the siren under the hood to the

vehicle’s metal body. Mount as close to
the grill as possible for best sound. The
siren must not touch the engine. Mount
with the mouth facing down so water will
not collect inside the siren.

B. Connect the siren’s BLACK WIRE directly to

the vehicle’s metal chassis. Scrape paint
from the metal surface, and use a factory
grounding bolt or a star washer.

C. Connect the alarm’s PINK WIRE directly to

the siren’s RED WIRE.

4. 8-wire connector, 3 x ORANGE WIRES

(to flash pos. or neg. parking lights),

fig. 3

A. Determine if the parking lights are

positively or negatively switched — Using a
VOM meter, test the wires coming from the
parking light switch. Look for a wire which
changes polarity when the parking lights
are turned on:

(1) Positive (+) parking light system — If a

wire goes to +12VDC when the
parking lights are turned on, but is not
+12VDC with the parking lights turned
off, this is the

(+) parking light wire

(See fig. 3a)

(2) Negative (–) parking light system — If

a wire goes to ground when the
parking lights are turned on, but is not
ground with the parking lights turned
off, this is the

() parking light wire

(See fig. 3b)

(3) NOTE:

a. Most vehicles have (+) parking

light systems. A few (mainly
Japanese) have (–) parking light
systems (the (–) signal usually
triggers a relay to send +12VDC to
the parking lights).

b. If the voltage on the (+) or (–)

parking light wire varies when you
dim or brighten the interior lights,
then this is not the correct wire.

CURRENT SENSING

A. Program the alarm for switch sensing only,

or for both current & switch sensing.

B. Current sensing does not trigger the alarm

until 4 seconds after the alarm is armed.

C. If the alarm is programmed for current

sensing, but does not detect the opening
of a door, it is possible the domelights do
not draw enough current. In this case, try
a brighter domelight (check the vehicle
manufacturer’s specifications), or connect
a non-polarized capacitor (47

F or larger)

in parallel across the domelight.

D. Note regarding current sensing:

(1) If the domelight burns out or is

constantly left ON, the alarm will not
detect the doors opening.

(2) If current sensing and passive arming

are desired, connect the door pin
switches to the alarm. Otherwise the
alarm will not arm properly.
