Do not disconnect the battery if the vehicle has an anti-theft coded radio. If equipped
with an airbag, avoid disconnecting the battery if possible.
IIMMPPOORRTTAANNTT!!Please read this entire installation guide before beginning the installa-
tion. The installation of this security system requires interfacing with many of the vehi-
cle’s systems. Many new vehicles use low-voltage or multiplexed systems which can
be damaged by low resistance testing devices, such as test lights or logic probes. Test
all circuits with a high-quality digital multi-meter before making the connections.
IMMPPOORRTTAANNTT!!Many airbag systems will display a diagnostic code through their warn-
ing light after they lose power. Disconnecting the battery requires this code to be
erased, a procedure that can require a trip to the dealer.
before beginning the installation:
zCheck with the customer to determine the integrated LED/Valet switch location.
zRemove the domelight fuse. This prevents accidentally draining the battery.
zRoll down a window to avoid being locked out of the car.
after the install:
zTest all functions. The “Using Your System” section of the Owner’s Guide is very
helpful when testing.
zWhen testing, don’t forget that this system is equipped with Nuisance Prevention®Circuitry.
NPC™can bypass both sensor zones, making them seem to stop working.
zCarefully reassemble the under-dash trim panels.
zInspect the engine compartment for tools that may have been left behind.

deciding on component location
control module
Never put the control module in the engine compartment!
The first step in hot-wiring a vehicle is removing the driver's side underdash panel to
access the starter and ignition wires. If the control module is placed just behind the
driver's side dash it can easily be disconnected.
When locating the control module, try to find a secure location that will not require
you to extend the harnesses’ wires (they are 1.5 meters long). Keep it away from the
heater core (or any other heat sources) and any obvious leaks.
Some good control module locations: Above the glove box, inside the center console,
above the underdash fuse box, above the radio, etc.

integrated LED/Valet®switch
Things to remember when positioning the integrated LED/Valet®switch:
• It should be visible from both sides and the
rear of the vehicle, if possible.
• It needs at least 1-1/2" clearance to the rear.
• It is easiest to use a small removable panel,
such as a switch blank or a dash bezel.
Remove it before drilling your 5/16" hole.
IIMMPPOORRTTAANNTT!!Do NNOOTTuse a step drill bit (unibit) for drilling the 5/16” hole. It is rec-
ommended to use a 5/16” drill bit. Use care to ensure the hole is drilled straight.
Drilling at an angle can cause product malfunction.
starter kill relay
If the Starter Kill Relay or it’s connections are immediately visible upon removal of the
underdash panel, they can easily be bypassed. Always make the relay and its con-
nections difficult to discern from the factory wiring! Exposed yellow butt connectors do
not look like factory parts, and will not fool anyone! For this reason, routing the starter
kill wires away from the steering column is recommended.
connecting your wires
Now that you have decided where each component will be located, you’re going to
find the wires in the car that the security system will be connected to.
IIMMPPOORRTTAANNTT!!Do not use a 12V test light to find these wires! All testing described in
this manual is described using a digital multimeter.
obtaining constant 12V
We recommend two possible sources for 12V constant: The (+) terminal of the battery,
or the constant supply to the ignition switch. AAllwwaayyssiinnssttaallllaaffuusseewwiitthhiinn1122iinncchheessooff
tthhiissccoonnnneeccttiioonn..

IIMMPPOORRTTAANNTT!!Do not remove the fuse holder on the red (H1/11) wire. It ensures that
the control module has it’s own fuse, of the proper value, regardless of how many
accessories are added to the main power feed.
finding the 12V switched ignition wire
The ignition wire is powered when the key is in the run or start position. This is
because the ignition wire powers the ignition system (spark plugs, coil) as well as the
fuel delivery system (fuel pump, fuel injection computer). Accessory wires, on the other
hand, lose power when the key is in the start position to make more current available
to the starter motor. Use the following procedure to find (+)12V with your multimeter.
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the ignition wire.
The steering column harness or ignition switch harness is
an excellent place to find this wire.
4. Turn the ignition key switch to the run position. If your
meter reads (+)12V, go to the next step. If it doesn’t, probe
another wire.
5. Now turn the key to the start position. The meter dis-
play should stay steady, not dropping by more than a few
tenths of a volt. If it drops close to or all the way to zero,
go back to step 3. If it stays steady at (+)12V, you have
found an ignition wire.

finding a parking light wire
The parking light wire is often found near the switch. Many cars have the switch built
into the turn signal lever, and in these cars the parking light wire can be found in the
steering column. The same wire is often available in the kick panel or running board.
(+) parking light wire
Use the following procedure to find (+) parking light wire with your multimeter.
1. Set to DCV or DC voltage (12V or 20V
is fine).
2. Attach the (-) probe of the meter to
chassis ground.
3. Probe the wire you suspect of being the
parking light wire. Usually, the area
near the headlight/parking light switch
is an excellent area to start, as is the
kick panel.
4. Turn on the parking lights. If your meter shows (+)12V, turn off the parking lights
and make sure it goes back to zero.
5. If it does return to zero, turn the parking lights back on and, using the dash light
dimmer control, turn the brightness of the dash lights up and down. If the meter
changes more than a volt when using the dimmer, look for another wire. If it
stays relatively close to (+)12V, you have found your parking light wire.
(-) parking light wire
Use the following procedure to find (-) parking light wire with your multimeter.
1. Set to DCV or DC voltage (12V or 20V
is fine).
2. Attach the (+) probe of the meter to
+12V.
3. Probe the wire you suspect of being the
parking light wire. Usually, the area
near the headlight/parking light switch
is an excellent area to start, as is the
kick panel.

4. Turn on the parking lights. If your meter shows (+)12V, turn off the parking lights
and make sure it goes back to zero.
5. If it does return to zero, turn the parking lights back on and, using the dash light
dimmer control, turn the brightness of the dash lights up and down. If the meter
changes more than a volt when using the dimmer, look for another wire. If it
stays relatively close to (+)12V, you have found your parking light wire.
finding the door pin switch circuit
The best places to find the door switch wire are:
At the pin switch: When testing at the pin switch, check the wire to ensure that it “sees”
all the doors. Often, the passenger switch will cover all the doors even if the driver’s
switch will not.
At the dome light: This may not be your best choice if the vehicle has delayed domelight
supervision, but it will work in vehicles with completely diode-isolated pin switches.
Often the door switch wires, described above, can also be found in the windshield pil-
lars, running boards or kick plates.
Use the following procedure to find the door pin switch wire with your multimeter.
1. Set to DCV or DC voltage (12V or 20V is fine).
2. In most cars, fasten the (+) probe of your meter to (+)12V constant.
3. Probe the wire you suspect of being the door trigger wire. If the meter reads
(+)12V when any door is opened and the meter goes to 0 with the door closed,
you have found a trigger wire.
NNOOTTEE: Make sure the wire you use “sees” all the doors! Some newer vehicles lack
standard-type pinswitches. The dome light in these vehicles is turned on when the door
handle is lifted. These usually have a wire coming out of the door into the kick panel
which will provide a (-) trigger for all doors.

supplied fuse. Connect to the battery positive terminal or the constant 12V supply to
the ignition switch.
NNOOTTEE::Always use a fuse within 12 inches of the point you obtain (+)12V. Do not
use the 15A fuse in the harness for this purpose. This fuse protects the module itself.
HH11//1122RREEDD//WWHHIITTEE((--))220000mmAAaauuxxiilliiaarryycchhaannnneell//ddeellaayyeeddaacccceessssoorryyoouuttppuutt::If pro-
grammed for an auxiliary output, this wire will provide a (-) pulse when the lock but-
ton on the factory transmitter is pressed twice within three seconds. This output can be
used to control optional accessories. If programmed for delayed accessory output, this
wire will provide (-) ground when the ignition is turned off and will continue to output
(-) ground until a door is opened then closed. This can be used to energize the acces-
sory circuit in the vehicle to keep the radio and other accessories on after the ignition
is turned off.
IIMMPPOORRTTAANNTT!!Never use this wire to drive anything but a relay or a low-current input!
This transistorized output can only supply (-) 200 mA, and connecting directly to a sole-

be used to honk the vehicle’s horn. It provides a pulsed output when the security sys-
tem is armed/disarmed and in the triggered sequence or in panic mode. In most vehi-
cle’s with (-) horn circuits this wire can control the vehicle’s horn without adding a
relay. If the vehicle has a (+) horn circuit, an optional relay must be used to interface
with the vehicle’s horn circuit.

vehicles operate this way. If this is the case connect the RED wire to the passenger
unlock motor wire. When testing this wire be sure that it shows 12V (+) ONLY when
the unlock button on the factory transmitter is pressed the second time to unlock the
passenger doors. If the factory keyless entry system unlocks all of the doors at the
same time, it is recommended that the H2/7 YELLOW/BLACK wire be used for dis-
arm defeat input.
NNOOTTEE::The H2/3 wire connection is not required if using H2/7 YELLOW/BLACK as a
disarm defeat wire.
HH22//44BBLLUUEEddiissaarrmmiinnppuutt::Connect the BLUE wire to a wire that changes state when the
doors are unlocked using the factory keyless entry transmitter. If the factory transmitter
unlocks the driver’s door first, the BLUE wire must be connected to the wire that changes
state when the driver’s door is unlocked by itself. In this case, find the driver’s door
unlock motor wire. In most vehicle’s this wire can be found in the driver’s kick panel.
NNOOTTEE::Some vehicles (some models of the Honda, GM and Ford) have long door
lock pulses. These long pulses may interfere with the disarm function of this system
when unlocking all doors using the factory OEM remote. Use the supplied door unlock
pulse adapter for these vehicles. Refer to the diagram below.
