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 instant trigger 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.
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. Always install a fuse within 12 inches
of this connection.

© 2003 directed electronics, inc. 7
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.
you have determined the wire color, the easiest place to connect to the wire is often at
the kick panel, at the windshield pillar, or in the running board. When an easy loca-
tion is not available, running a wire to the domelight itself is often the best solution.
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.

H1/1 ORANGE (-) 500 mA ground-when-armed output: This wire supplies a (-)
ground as long as the system is armed. This output ceases as soon as the system is
disarmed. This wire controls operation of the pre-wired starter kill relay and can be
used to control other optional accessories.
NNOOTTEE::If connecting the orange wire to control another module, such as a 529T or
530T window controller, a 1 amp diode (type 1N4004) will be required. Insert the

H1/2 WHITE light flash output: As shipped, this wire should be connected to the (+)
parking light wire. It will supply a (+) 10A output. If the light flash polarity fuse jumper
inside the unit is moved to the opposite position (see Internal Jumpers), this wire sup-
plies a (-) 10A output. This is suitable for driving (-)parking light wires.

H1/4 BLACK/WHITE (-) 200 mA domelight-supervision output: Connect this wire to
the optional domelight supervision relay.
IIMMPPOORRTTAANNTT!!This output is only intended to drive a relay. It cannot be connected
directly to the domelight circuit, as the output cannot support the current draw of one
or more bulbs.
H1/5 GREEN (-) door trigger input: Most vehicles use negative door trigger circuits.
Connect the green wire to a wire which shows ground when any door is opened. In
vehicles with factory delays on the domelight circuit, there is usually a wire that is
unaffected by the delay circuitry.

H1/6 BLUE (-) instant trigger: This input will respond to a negative input with an
instant trigger. It is ideal for hood and trunk pins and will report on zone one.
H1/7 VIOLET (+) door trigger input: This wire is used in vehicles that have a positive
(+) switched dome light circuit . Connect the violet wire to a wire that shows (+)12V
when any door is opened, and ground when the door is closed.
H1/8 BLACK (-) chassis ground connection: Connect this wire to bare metal, prefer-
ably with a factory bolt rather than your own screw. Screws tend to either strip or
loosen with time. All components, should be grounded to the same point in the vehi-
cle if possible.

14 © 2003 directed electronics, inc.
H1/9 YELLOW (+) ignition input: Connect this wire to the (+)12V ignition wire. This
wire must show (+)12V with the key in Run position and during cranking. Take care
to insure that this wire cannot be shorted to the vehicle chassis at any point.
H1/10 BROWN (+) siren output: This output can be used if an optional siren is
installed. Connect this to the RED wire of the siren. Connect the BLACK wire of the
siren to (-) chassis gound, preferably at the same point as the control module’s BLACK
ground wire.
H1/11 RED (+)12V constant power input: Before connecting this wire, remove the
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.
H1/12 RED/WHITE (-) 200mA auxiliary channel/delayed accessory output: 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

© 2003 directed electronics, inc. 15
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-
noid, motor, or other high-current device will cause the module to fail.
NNOOTTEE::Zones 2 and 4 are shunted when this channel becomes active. Zones 2 and
4 reactivate 5-seconds after this channel’s output ceases.

H2/1 BROWN (-) horn honk output: This wire supplies a 200 mA (-) output that can
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.
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-
noid, motor, or other high-current device will cause the module to fail.
H2/2 GREEN for arm input: Connect either this GREEN or H2/4 BLUE wire to a wire
that changes state when the doors are locked using the factory keyless entry transmit-
ter. This wire can accept a positive (+) or negative (-) input. The vehicle’s power door
lock motor wire is ideal.
NNOOTTEE::These wires (H2/2 and H2/4) can be used for arm and disarm interchangeably.
H2/3 RED disarm defeat input: This wire is used to prevent the interior door lock
switches from disarming the system. To determine the best location to interface this
wire, first test the operation of the remote keyless entry system. When unlocking the
doors with the factory remote transmitter, does the driver’s door unlock first? Most
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 (+) when the
unlock button on the factory transmitter is pressed twice. If the factory keyless entry
system unlocks all of the doors at the same time, connect this wire to the unlock wire
coming from the lock switch.
H2/4 BLUE disarm input: (See H2/2 GREEN description). Connect the opposite 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.
H2/5 GRAY trunk release/sensor shunt input: This input is used to bypass the sen-
sor inputs when the trunk is opened using the factory keyless entry system or trunk
release relay. When the system receives a (+) input on this wire, zones 2 and 4 (if set
in the features settings) are bypassed for 3-seconds. If during that 3-seconds, ground
is applied to the H1/6 BLUE wire zones 2 and 4 will remain bypassed until the ground
input is removed. This means that when the trunk is open with the factory transmitter
the only triggers that remain active while the trunk is open are the doors and ignition.
3-seconds after the trunk is closed the bypassed zones again become active.
The following table lists the commonly used lock/unlock motor wire colors.
H2/6 VIOLET/BLACK no function.
H2/7 YELLOW/BLACK light flash monitor input: This input monitors the factory sys-
tem light flash output. Connect this wire to the light flash wire that flashes when the
factory transmitter is used. This may be a status LED, parking lights, reverse lights, etc.,
depending on the vehicle type and manufacturer. This wire can accept a (+) positive
or (-) negative input.
