When the system receives the code controlling Channel 2, for longer than 1.5 seconds, the red/white wire will
supply an output as long as the transmission continues. This is often used to operate a trunk/hatch release or
other relay-driven function.

IIMMPPOORRTTAANNTT!!Never use this wire to drive anything but a relay or a low-current input! The tran-
sistorized output can only supply 200 mA of current. Connecting directly to a solenoid, motor,
or other high-current device will cause it to fail.
Before connecting this wire, remove the supplied fuse. Connect to the positive battery terminal or the constant
12V supply to the ignition switch.
NNOOTTEE::Always use a fuse within 12 inches of the point you obtain (+)12V power. Do not use the
15A fuse in the harness for this purpose. This fuse protects the module itself.
Connect this to the red wire of the siren. Connect the black wire of the siren to (-) chassis ground, preferably at
the same point you connect the control module’s black ground wire.
Connect this wire to an ignition source. This input must show (+)12V with the key in run position and during
cranking. Make sure that this wire cannot be shorted to the chassis at any point. This wire will report Zone 5.

Remove any paint and connect this wire to bare metal, preferably with a factory bolt rather than a screw. (Screws
tend to strip or loosen with time.) We recommend grounding all components, including the siren, to the same point.
This wire is used in vehicles that have a positive (+) switched domelight circuit. Connect the violet wire to a
wire that shows (+)12V when any door is opened, and ground when the door is closed. This wire will report Zone 3.
This wire will respond to a negative input with an instant trigger. Inputs shorter than 0.8 seconds will trigger
the Warn Away response, while triggers longer than 0.8 seconds will instantly trigger the full alarm cycle. This
wire is ideal for hood and trunk pins and will report on Zone 1. This wire can also be used with Directed
Electronic’s 506T Glass Breakage Sensor, as well as other Directed Electronic’s single stage sensors. The H1/7 BLUE
multiplex trigger wire can be used to shunt sensors during operation, using the auxiliary channels. When any of
the auxiliary channels are transmitted, the H1/7 BLUE wire monitors for a ground. If ground is detected within
5 seconds of transmission, the sensors and the multiplex trigger input on the BLUE wire will be shunted until 5
seconds after the ground is removed. This allows the customer to access the trunk, remote start the vehicle, or
roll the windows down without first disarming the alarm. (See
Bypassing Sensor Inputs section of this guide.)

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. This wire will report Zone 3.
Connect this wire directly to the domelight circuit in the vehicle. The on-board relay will drive circuits up
to 20 amperes. The polarity of this output is determined by the connection of the H2/G input wire in the Door
Lock Harness.
NNOOTTEE::If the H2/G input wire is not connected, there will be no output on this wire.
When the system receives the code controlling Channel 3, the white/blue wire will supply an output as long as
the transmission continues. Use for options such as 556611TTValet Start system, 552299TTor 553300TTpower window con-
trollers, etc.
IIMMPPOORRTTAANNTT!!Never use this wire to drive anything except a relay or a low-current input! The
transistorized output can only provide 200 mA of current, and connecting directly to a solenoid,
motor, or other high-current device will cause it to fail.

As shipped, this wire should be connected to the (+) parking light wire. If the light flash polarity jumper inside
the control module is moved to the opposite position (see
Internal Programming Jumper section of this guide),
this wire supplies a (-) 200 mA output. This is suitable for driving (-) light control wires in Toyota, Lexus, BMW,
some Mitsubishi, some Mazda, and other model cars.

NNOOTTEE::For parking light circuits that draw 10 amps or more, the internal jumper must be switched
to a (-) light flash output. (See the Internal Programming Jumper section of this guide.) PP//NN88661177
or a standard automotive SPDT relay must be used on the H1/11 light flash output harness wire.
This wire supplies (-) ground as long as the system is armed. This output ceases as soon as the system is disarmed. This
wire can be used to turn on an optional sensor or to control an optional accessory, such as a window module or pager.

*VIOLET and VIOLET/BLACK wires are common at the fuse holder.
This wire determines what the output polarity of H1/9 will be. If the door pin circuit is negative, connect to
chassis ground. If the door circuit is positive, connect to a fused 12V source.
IIMMPPOORRTTAANNTT!!The H2/G wire is not required for wiring the door locks. Depending on the type of
door lock system, there may be additional wires in the Door Lock Harness (H2) that are not
required used in wiring the door locks.
The system has door lock relays on-board, and can directly interface with most electric power door lock systems
drawing 20 amps or less. These can also drive aftermarket actuators directly. (Some vehicles require that an after-
market actuator be added to the driver’s door to allow system control, see
Type D wiring section).
The easiest way to determine which type of door lock system you are working with is to remove the master
locking switch itself, which is usually on the driver’s door or on the center console. Once you have determined
which type of factory door lock circuit you are working with, and the color codes of the switch wires to be used,
you can usually simplify the installation by locating the same wires in the vehicle’s kick panel. If no central
locking switch is found, the installation may require a door lock actuator.
NNOOTTEE::Always retest the wires in the kick panel to be sure they function the same way as the
wires on the switch.

There are eight common types of door lock circuits (some vehicles use more unusual systems):
■TTyyppeeAA::Three-wire (+) pulse controlling factory lock relays. Most GM, some Ford and Chrysler, 1995 Saturn,
some new VW, newer BMW.
■TTyyppeeBB::Three-wire (-) pulse controlling factory lock relays. Most Asian vehicles, early Saturn, some BMW and
Porsche.
■TTyyppeeCC::Direct-wired reversing-polarity switches. The switches are wired directly to the motors. This type of
system has no factory relays. Most Fords, many GM two-doors cars and trucks, many Chryslers.
■TTyyppeeDD::Adding one or more aftermarket actuators. These include slave systems without an actuator in the
driver’s door, but with factory actuators in all the other doors. Type D also includes cars without power locks,
which will have actuators added. All Saabs before 1994, all Volvo except 850i, all Subaru, most Isuzu, and
many Mazdas. Some mid-eighties Nissans, pre-1985 Mercedes-Benz and Audi.
■TTyyppeeEE::Electrically-activated vacuum systems. The vehicle must have a vacuum actuator in each door. Make
sure that locking the doors from the driver's or passenger side using the key activates all the actuators in
the vehicle. This requires a slight modification to the door lock harness. Mercedes-Benz and Audi 1985 and
newer.
■TTyyppeeFF::One-wire system - cut to lock, ground to unlock. This system is found in late-model Nissan Sentras,
some Nissan 240SX, and Nissan 300ZX 1992 and later. It is also found in older Mitsubishis, and some early
Mazda MPV’s.
■TTyyppeeGG::Positive (+) multiplex. This system is most commonly found in Ford, Mazda, Chrysler and GM vehi-
cles. The door lock switch or door key cylinder may contain either one or two resistors.
■TTyyppeeHH::Negative (-) multiplex. The system is most commonly found in Ford, Mazda, Chrysler and GM vehi-
cles. The door lock switch or door key cylinder may contain either one or two resistors.
■Three-wire switches will have either a constant ground input or a constant (+)12V input, along with the
pulsed lock and unlock outputs to the factory relays.
■Many BMW’s and VW’s have no external switch. The switches are inside the actuator, and instead of pulsing,
the proper wires will flip-flop from (+)12V to (-) ground as the door locks are operated.
■Direct-wired switches will have a (+)12V constant input and one or two (-) ground inputs, along with two
output leads going directly to the lock motors.

1100© 2005 Directed Electronics, Vista, CA—all rights reserved
The system can control Type A door locks directly, with no additional parts. The switch will have three wires on
it, and one will test (+)12V constantly. The others will alternately pulse (+)12V when the switch is pressed to
the lock or unlock position.
If you cannot get to the switch, and you find a set of wires that pulse (+)12V alternately on lock and unlock,
make sure that it is not a Type C direct-wire system.
HHeerreeiissaatteesstt::Cut the wire that pulses (+)12V on lock, and then operate the switch to unlock.
■If all doors unlock, the vehicle uses a Type A system.
■If you lose all door lock operation in both directions, you are operating the master switch in a Type C system.
■If you lose all door lock operation of one or more, but not all motors, and other doors still work, you have
cut a wire leading directly to one or more motors You must reconnect the wire and search again for the actual
wires leading to the switch.
Many domestically-made GM vehicles use Type A locks. However, many more GM vehicles are Type C than in pre-
vious years. The full-size pickups (1989-up), many of the Blazers, the Corvette, ‘95 Cavalier/Sunfire 1993 and the
newer, Camero/Firebird all use Type C door locks, and cannot be controlled without a 451M. Almost all domesti-
cally-built Fords are Type C. Ford builds no type A systems. Chrysler builds both Type A and Type C, so proceed
with caution.
