GENERAL CONSIDERATIONS
IMPORTANT: THIS ALARM IS INTENDED FOR INSTALLATION
BY QUALIFIED PROFESSIONALS ONLY.
READ BOTH THIS MANUAL AND THE OWNERS MANUAL
COMPLETELY BEFORE BEGINNING THE INSTALLATION
1. Make sure all electrical connections are
securely soldered.
2. Do not run wires too tightly. Allow some
slack in case the wires are accidentally
pulled by someone servicing the vehicle in
the future. emember that wires may shrink
or break due to impact, heat, and so on.
3. Do not allow wires to rub against sharp
edges which could cause short circuits. Use
grommets when wires are run through holes
in the car body or firewall.
4. Protect and hide wires with flexible tubing or
by wrapping with electrical tape if possible.
Ideally, the wires should be indistinguishable
from the vehicles factory wiring.
5. Mount all plastic components away from
sources of extreme heat such as the exhaust
manifold or turbocharger to prevent melting.
Also mount all components away from areas
that receive water directly.
6. Mount all components in such a way that
they do not impair or interfere with the
normal operation of the cars moving parts.
7. Mount all components and run all wires so
they cannot be easily reached from
underneath the vehicle.
BEFORE YOU START, DONT FORGET:
1. Ask the customer where to install the LED. It
should be visible from the right and left sides
of the car. It should not be exposed to direct
sunlight.
2. Ask the customer where to install the push-
button switch. It should be inconspicuous,
yet easy to reach in case of an emergency.
3. Turn the domelight OFF, or remove the
domelight fuse, to save car battery power
during the installation. (But turn the
domelight ON or replace the fuse before
testing using current sensing.)
IMPORTANT:
THIS MANUAL OFFERS GENERAL
GUIDELINES ONLY. INSTALLATION WILL
VARY FROM VEHICLE TO VEHICLE.
SECO-LARM IS NOT RESPONSIBLE FOR
INJURIES OR DAMAGES WHICH RESULT
FROM INCORRECT INSTALLATION OF THIS
ALARM SYSTEM.
DISCONNECT THE FUSES FROM THE
ALARMS RED AND ORANGE WIRES BEFORE
BEGINNING THE INSTALLATION. PLUG
BACK IN ONLY AFTER THE INSTALLATION IS
DONE AND CHECKED.
TEST ALL WIRES CAREFULLY BEFORE
CUTTING OR SPLICING. TO AVOID
DAMAGING THE VEHICLES ELECTRICAL
E UIPMENT, USE A TEST METER, NOT A
TEST LIGHT.
IF THE VEHICLE IS E UIPPED WITH AN
ANTI-THEFT RADIO OR AN AIR BAG, DO
NOT DISCONNECT THE BATTERY.

Connector 2 (8-pin connector)
3 x ORANGE WIRES (to flash positi e or
negai e parking lights), fig. 1
A. Determine if the parking lights are positively
or negatively switched  Using a VOM meter,
test the wires coming from the parking light
switch. Find 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 does not show
any voltage with the parking lights
turned OFF, this is the (+) parking light
wire.
(2) Negative () parking light system  If a
wire goes to ground when the parking
lights are turned ON, but does not show
any ground with the parking lights
turned OFF, this is the () parking light
wire.
(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.
B. Connect the fused O ANGE WI E:
(1) Positive (+) parking light system 
Connect the fused O ANGE WI E
directly to a source of unswitched
+12VDC at the fuse box.
(2) Negative () parking light system 
Connect the fused O ANGE WI E
directly to a solid chassis ground.
C. Connect one or two non-fused O ANGE
WI Es:
(1) Single-wire parking light systems  Most
vehicles have a single circuit which
controls all parking lights. In this case,
connect both non-fused O ANGE WI Es
to the (+) or () parking light wire.
Connector 2 (8-pin connector)
RED WIRE (5A fuse, to +12VDC)
emove 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.
NOTE  For quiet power-up, turn the ignition
ON before plugging in the red wires fuse.
IMPORTANT  FO SAFETY, DO NOT
INC EASE THE LENGTH OF THE ED WI E.
IMPORTANT  DO NOT PLUG IN THE FUSE
UNTIL ALL OTHE CONNECTIONS A E MADE.

(2) Dual-wire parking light systems  A few
vehicles (mainly European) have
separate circuits for the parking lights on
the right and left sides of the vehicle.
In this case, connect one non-fused
O ANGE WI E to the right-side circuit,
and the other to the left-side circuit.
D. Dual Power Protection (DPPTM)
With DPP, if you connect the fused O ANGE
WI E to +12V, it becomes a second power
source for the alarm brain if the fused ED
WI E is cut. This works only if this O ANGE
WI E is connected to a separate source of
+12VDC from the ED WI E.
Connector 2 (8-pin connector)
BLACK WIRE (to chassis ground) , fig. 2
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.
Connector 2 (8-pin connector)
WHITE WIRE (to starter disable),
figs. 3a, 3b
Connect to an optional 30A relay to prevent the
car from starting when the alarm is armed.
A. Locate the starter solenoid wire (carries
power from the ignition switch to the starter
solenoid). This wire must show +12VDC
only when the ignition is in the start position.
B. Cut the starter solenoid wire.
C. Test the starter solenoid wire as follows:
(1) If the wire is cut before the engine is
started, the engine should not turn over.
(2) If the wire is cut while the engine is
running, there should be no effect.
D. Connect the WHITE WI E and the two halves
of the cut starter solenoid wire to the relay as
shown in fig. 3a.
E. If the engine still starts, connect terminal 86
to a wire which shows +12VDC when the
engine is both starting and running (fig. 3b).
F. NOTE regarding N.C./N.O. output  The
starter disable output is programmable for
N.C. or N.O. operation. Default is N.C.
(See P OG AMMING, page 18.) If N.O.
starter disable output is required, connect the
ignition switch side of the starter solenoid
wire to terminal 87 of the starter disable
relay instead of 87a. All other connections
are the same.
Connector 2 (8-pin connector)
PINK WIRE (to siren), fig. 4
A. Mount the siren under the hood to the
vehicles metal body 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.

C. Connect the alarms PINK WI E directly to
the sirens ED WI E.
Connector 2 (8-pin connector)
YELLOW WIRE (to ignition switch
oltage input)
Connect to a fuse or wire which outputs
+12VDC when the ignition key is in the ON and
STA T position, but not the ACC position. This
wire must be connected at all times to ensure
proper arming and disarming, as well as to
operate the VEPLe push-button switch.
Connector 3 (6-pin connector)
BLUE WIRE (neg. door trigger input),
fig. 5
A. Existing car door switches  Use a VOM
meter to locate a wire (usually in the drivers
kick panel) which shows ground when any
door is open, and which is not ground when
all the doors are closed. Connect to the
BLUE WI E. (NOTE  If this wire shows
+12VDC when a door is opened, see
PU PLE WI E below.)
B. If the vehicle (such as a delivery van) has no
existing car door switches  Mount a pin
switch in every door you wish to protect.
Connect each switch to the BLUE WI E.
Connector 3 (6-pin connector)
PURPLE WIRE (pos. door trigger input),
fig. 6
Use a VOM meter to locate a wire (usually in the
drivers kick panel) which shows +12VDC when
any vehicle door is open, and which is not
+12VDC when all the doors are closed.
Connect to the PU PLE WI E.
Connector 3 (6-pin connector)
BLUE/WHITE WIRE (negati e hood/
trunk trigger input), figs. 7 & 8
A. If the vehicle has a trunk switch, but no hood
switch  Use a VOM meter to locate the wire
which shows ground when the trunk is open,
and which is not ground when the trunk is
closed. Mount a pin switch in the hood.
Connect both to the BLUE/WHITE WI E as
shown in fig. 7.
B. If the vehicle has no existing hood or trunk
switches  Mount a pin switch in both the
hood and the trunk. Connect both switches
to the BLUE/WHITE WI E as shown in fig. 8.
Connector 3 (6-pin connector)
BROWN/WHITE WIRE ( (-) factory
honking horn output), fig. 9
Programmable - Supplies a pulsing 200mA
output to drive a (-) factory car horn relay.
A. Operation - When the alarm is triggered, this
wire pulses 200mA to activate the (-) factory
horn honk relay found in most vehicles. This
allows the alarm to honk the horns and blast
the siren at the same time.
B. Connection - Connect the B OWN/WHITE
WI E directly to the negative input of the
vehicles factory horn relay (it should show
() when the vehicles horn button is
pressed). Make sure this input draws less
than 200mA of current. Otherwise, add a
30A relay to honk the horns.

(1) When the alarm is disarmed, this wire
turns the domelights on for 30 seconds,
or until the ignition key is turned ON.
(2) When the alarm is triggered, this wire
flashes the domelights.
(3) When the ignition-controlled domelight is
enabled, turning OFF the ignition will
turn ON the domelight for 30 seconds.
B. Connection  Connect the G AY/BLACK
WI E via a 30A relay to the domelights.
Never connect the gray/black wire directly to
the domelights, as this will burn out the
domelight output, and possibly the entire
alarm brain.

3-Pin Door Lock Interface, figs. 12 to 15
To find the lock switching wire from the interior
switch with a VOM meter, lock the drivers door
via the interior central door lock switch. The lock
switching wire shows the status changed as long
as the interior central door lock switch is
pressed.
To find the unlock switching wire from the
interior switch with a VOM meter, unlock the
drivers door via the interior central door unlock
switch. The unlock switching wire shows the
status changed as long as the interior central
door unlock switch is pressed.
The B OWN wire in this connector is the unlock
switch defeat input. When connected to the
unlock switch lead in the vehicle, the unit will
disarm via the keyless entry system only -- the
switch will have no effect.
NOTE: If the unlock switch defeat is not desired,
connect the B OWN input wire to () chassis
ground prior to teaching the unit the door locks.
To find the passenger door unlock wire from the
interior central door lock switch with a VOM
meter, unlock all the doors via the OEM remote.
The passenger door unlock wire changes status
during the unlock operation.
There are four main types of keyless entry
systems. Connect the 3-pin white connectors
three wires according to type:
A For vehicles WITH drivers door priority
unlock and with relays inside the OEM
keyless module -- This is common with most
Ford and some GM vehicles. See fig. 12.
B. For vehicles WITH drivers door priority
unlock and with relays outside the OEM
keyless module -- Common with many 4-
door GM vehicles. See fig. 13.
C. For vehicles WITHOUT drivers door priority
unlock and with relays outside the OEM
keyless module, and which require the
disarm defeat function -- This is common
with import vehicles and many Jeep vehicles.
See fig. 14
D. For vehicles WITHOUT drivers door priority
unlock and with relays outside the OEM
keyless module, but which do not require the
disarm defeat function -- This is common
with import vehicles and with many Jeep
vehicles. See fig. 15.
Note: For C and D above, figs. 14 and 15 show
how to install the system in a way that prevents
disarming the ENFO CE alarm via the interior
central door lock switch.
IMPO TANT: Insert a 1N4004 diode as shown
in the diagrams. Near the relays is the best
location to insert this diode. Failure to insert the
diode at the correct point will allow the
ENFO CE alarm to be disarmed by one of the
power door lock switches inside the car. If the
relays are difficult to locate, call SECO-LA M
technical support.

These 3 wires allow the alarm to control the
power door lock/unlock systems of most vehicles
without external relays. However, one or two
relays may be required in some cases.
The alarm has a built-in timer which is pre-set
for 0.5 seconds, but which can be programmed
for 3.5 seconds.
Types of door lock/unlock systems  At the time
this manual was completed, there were seven
common types of power door lock/unlock
systems in use:
A. Negative relay switching to factory actuators
 The factory door lock switch has 3 wires.
One wire always shows ground. The LOCK
WI E becomes ground when the door is
locked, and sends a pulse to a factory relay
to lock the doors. The UNLOCK WI E
becomes ground when the door is unlocked,
and sends a pulse to a factory relay to
unlock the doors. Most Japanese cars use
this system. THIS IS THE MOST COMMON
TYPE OF POWE DOO LOCK SYSTEM.
See fig. 16.
B. Positive relay switching to factory actuators
 The factory door lock switch has 3 wires.
One wire always shows +12VDC. The
LOCK WI E becomes +12VDC when the
door is locked to pulse a factory relay to lock
the doors. The UNLOCK WI E becomes
+12VDC when the door is unlocked to pulse
a factory relay to unlock the doors. Most
General Motors cars use this system.

C. Positive reversal switching to factory
actuators  The factory door lock switch
typically has 5 wires. Two wires always show
ground, and one always shows +12VDC.
The LOCK WI E shows ground at rest and
during unlock, but shows +12VDC when the
door is locked. The UNLOCK WI E shows
ground at rest and during lock, but shows
+12VDC when the door is unlocked. Many
GM trucks, Fords, and Chryslers use this
system. See fig. 18.
D. Single wire, polarity switching  The factory
door lock switch uses a single wire to control
the door lock and unlock operation. The
single LOCK/UNLOCK WI E shows ground
when the doors lock, and +12VDC when
they unlock. This is found on most Mercedes
Benz and on some other European cars.
See fig. 19.
E. Single wire, positive shunt switching  This
system uses a single wire to activate the door
locks. Applying +12VDC on the LOCK/
UNLOCK WI E causes the doors to unlock,
and removing the +12VDC (not applying
ground) causes the doors to lock. Found on
some Ford Probes. See fig. 20.
F. Single wire, negative shunt switching  This
system uses a single wire to activate the door
locks. Applying ground on the LOCK/
UNLOCK WI E causes the doors to unlock,
and removing the ground (not applying
+12VDC) causes the doors to lock. Found
on some Mazdas and Nissans. See fig. 21.
G. Aftermarket door lock actuators  If the
vehicle does not have power door locks,
install aftermarket actuators according to the
suppliers instructions. (If the vehicle has
power door locks on all doors except the
drivers door, install one aftermarket
actuator on the drivers door. Includes some
Volvos, SAABs, and assorted Japanese
models.) See fig. 22.

B. Plug the sensor into the alarm brain's 4-pin
connector.
C. Set the sensitivity:
(1) Turn the pre-intrusion (1st stage)
sensitivity to maximum (clockwise).
(2) Test the trigger (2nd stage) sensitivity by
rapping hard on the vehicle to simulate
an attack. (Do not hit the window.)
Adjust the sensitivity by turning the
trigger adjustment pod clockwise (more
sensitive) or counterclockwise (less
sensitive).
(3) Once trigger sensitivity is set, test pre-
intrusion (1st stage) sensitivity by lightly
knocking on the vehicle to simulate
someone bumping the car. Adjust the
sensitivity by turning the pod clockwise
(more sensitive) or counter-clockwise
(less sensitive).
(4) NOTE:
a. Changing trigger sensitivity also
affects pre-intrusion sensitivity.
b. When trigger sensitivity is set to
minimum, the shock sensor cannot
trigger the alarm (equivalent to
turning the shock sensor OFF).
Pre-intrusion is also turned OFF.
c. When sensitivity is set to maximum,
the shock sensor is very sensitive.
This may cause unnecessary chirps
and/or false alarms.
d. To prevent false alarms, the shock
sensor and auxiliary sensors will not
trigger the alarm until 4 or 60
seconds (depending on the remote
used)after the alarm is armed and
no further motion is detected ( see
sensor delay times on page 19).
NOTE  To connect more than one
SECO-LA M dual-stage shock, microwave, or
glass break sensor, use an S -199-315
Y-connector. (See fig. 24.)
NOTE  To install non-SECO-LA M auxiliary
sensors  Splice into the shock sensor's wire
harness as shown in fig. 25. For single-stage
auxiliary sensors, do not use the YELLOW WI E.
IMPORTANT  These four wires are transistor
+12VDC or transistor ground inputs and
outputs with max. ratings of 200mA. Take care
when connecting accessories to these wires.

C. Note regarding current sensing:
(1) If the domelight burns out or is con-
stantly 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.
A. The alarm has a current sensing delay of 60
seconds when a factory remote is used and
a current sensing delay of 4 seconds after
the alarm arms when the optional
ENFO CE remote is used. In other words,
current sensing does not trigger the alarm
until 4 or 60 secs. after the alarm is armed.
B. 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

(4) Within 15 seconds, push any button of
the first transmitter to be learned. At this
time, all previous codes are deleted, and
the alarm learns this transmitter's code.
1 chirp confirms code is learned. (If no
button is pressed within this 15-second
period, code learning is exited, and old
codes are retained.)
(5) Within 15 seconds, push any button of

B. Exit the code learning procedure  The
alarm chirps the siren two times, exits the
code learning mode, and is disarmed after
learning the fourth transmitter's code, or if
you turn the ignition switch ON, or if you do
nothing for 15 seconds.
Note  This section applies only if the optional
ENFO CE remotes are used.
The alarm can learn a max. of 4 remotes. F
Code Wash deletes all previous remotes when
any new remote is learned. This prevents
unauthorized use of lost or stolen transmitters,
and, because the user's transmitter no longer
works, alerts the user if someone has secretly
code learned a new transmitter. However, it also
means that, when code learning is being done,
ALL THE USE 'S T ANSMITTE S MUST BE CODE

A. Door Lock  Test the door lock by pressing
the lock and unlock buttons. If the door lock
does not respond, shut down then reconnect
the alarm units power, or manually perform
the door lock/unlock priority learn operation
(see above).
B. Testing wire connections  Often, when trying
to trace a problem between a trigger input,
wiring, and the alarm brain, one place to
test is at the alarm brain itself. Set the VOM
for (+) or (-), depending on the trigger, then
probe the appropriate wire near the alarm
brain while testing the trigger. For instance,
to determine why a
(-) door trigger is not working, probe and
test the BLUE WI E of the 6-pin connector
near that connector. If the BLUE wire shows
(-) when the door is opened, then the
problem may be caused by the user not
arming the alarm correctly, or the alarm
brain may be defective. But if the BLUE wire
does not show (-) when the door is opened,
the problem may be a loose or defective pin
switch or wire connection.
C. Sensor delay times  The various sensors
have a short delay from the time the alarm is
armed until the sensor can be triggered.
Therefore, after arming the alarm, wait until
after the delay period before testing the
sensor to be sure that sensor is operating
properly:
(1) Hardwired triggers  4-second delay.
(2) Shock (auxiliary sensors) and Current
sensing  60 second delay for factory
remote and 4-second delay for the
optional ENFO CE remote.
D. Triggered zone recall  When the alarm is
armed, trigger any one zone of the car. Then
disarm the alarm. The number of flashes on
the LED will indicates which zone was last
triggered, regardless of when it was triggered:
(1) 1 flash  The ignition was triggered.
(2) 2 flashes  Panic was triggered.
(3) 3 flashes  Shock or auxiliary sensor was
triggered.
(4) 4 flashes  A door was opened.
(5) 5 flashes  The hood or trunk was
opened.
(6) 6 flashes  The current sensor was
triggered.
This memory display will stop only after 15
seconds of inactivity.
TIPS FOR TESTING THE ALARM
DOOR LOCK/UNLOCK POLARITY LEARN MODE
When the SLI 820 /-4 is powered up for the first
time, it is necessary to manually teach the SLI
820 /-4 the correct polarity as follows:
1. Turn the ignition switch ON.
2. Within 15 seconds, press and hold the VEPLe
switch for 4 seconds. The siren will chirp
once to confirm the alarm has entered the
polarity learn mode. Then the alarm will
automatically learn the arm input, disarm
input and disarm defeat input.
3. Turn the ignition switch OFF and siren will
chirp twice.
(7) Exit programming mode  Three ways:
a. No VEPLe button activity for 15
seconds; or
b. Turn the ignition switch OFF; or
c. Press and release the VEPLe button
to choose the 14th feature.
B. NOTE:
(1) When the programming mode is exited,
the siren chirps twice.
(2) Programming chirps are not deleted
with one-time or permanent chirp
delete.
