installation points to remember
This system has been designed to provide the ultimate in convenience to both the dealer and the end user. The
microprocessor at the heart of the system utilizes a sophisticated “Learn Routine” to program transmitters as
well as configure operation settings. Transmitter codes and operations settings are stored in “EEPROM” and will
remain in memory even if the system’s main power is disconnected for extended periods of time. Please take the
time to read this guide thoroughly prior to installing the system.
Do not disconnect the battery if the vehicle has an anti-theft coded radio. If equipped with an airbag, avoid dis-
connecting the battery if possible.
IMPORTANT! Many airbag systems will display a diagnostic code through their warning 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:
■Check with the customer on status LED location.
■Remove the domelight fuse. This prevents accidentally draining the battery.
■Roll down a window to avoid being locked out of the car.
After the installation:
■Test all functions. The “Using Your System” section of the Owner’s Guide is very helpful when testing.
wiring the control unit
The wiring harness supplied with this unit is the standard 12-pin harness used by DEI security systems. Two wires
in the plug are not used. The functions of all the wires that are used in the primary harness are outlined in the
following Primary Harness (H1), 12-Pin Connector section. The wire connections are described in the Primary
Harness (H1) Wire Connection Guide section.

primary harness (H1) wire connection guide
This wire supplies a (-) 500 mA output as long as the system is armed. This output ceases as soon as the system
is disarmed. The orange wire is used to control the optional starter kill relay.
NOTE: 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 diode as shown below.
IMPORTANT! Never interrupt any wire other than the starter wire.
This wire provides a (-) 200mA output to flash the parking lights. This is suitable for driving (-) light control
wires in Toyota, Lexus, BMW, some Mitsubishi, some Mazda, etc. If the vehicle has a positive parking light circuit,
a relay must be used to flash the parking lights.
This wire provides a (-) 200 mA output whenever the transmitter code controlling Channel 3 is received. This
output will continue as long as that transmission is received. Use for options such as DEI’s 551T Valet®Start
system, 529T or 530T power window controllers, etc.
IMPORTANT! Never use this wire to drive anything except a relay or a low-current input! The tran-
sistorized 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.

Connect this wire to the optional domelight supervision relay as shown below:
IMPORTANT! 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 light bulbs.
The H1/6 BLUE output is used for progressive unlock. A progressive unlock system unlocks the driver's door when
the unlock (disarm) button is pressed and unlocks the passenger doors if the unlock (disarm) button is pressed
again within 15 seconds after unlocking the driver's door. The BLUE wire outputs a low current (-) pulse on the
second press of the unlock button of the transmitter. This negative unlock output is used to unlock the passen-
ger doors.

Type C (+) reversing polarity system: Wire relays as shown.
Connect this wire to bare metal, preferably with a factory bolt rather than your own screw (screws tend to either
strip or loosen with time). We recommend grounding all your components to the same point in the vehicle.
H1/8 BLACK (-) chassis ground connection

10 © 1999 Directed Electronics, Inc. Vista, CA
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 trigger the system
if the ignition is turned on before the unit is disarmed (doors unlocked with the remote). It will also honk the
vehicle’s horn and flash the parking lights (if connected).
This wire supplies a 200 mA (-) output that can be used to honk the vehicle horn. It outputs a single pulse when
locking the doors with the remote, and two pulses when unlocking with the remote. This wire will also output
pulses for 30 seconds when the Panic Mode is activated. If the vehicle has a (+) horn circuit, an outboard relay
can be used to interface with the system, as shown below.
Before connecting this wire, remove the supplied fuse. Connect to the positive battery terminal or the constant
12V supply to the ignition switch.
NOTE: 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.
H1/11 RED (+)12V constant power input
H1/10 BROWN (-) horn honk output

When the system receives the transmitter 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 functions.
IMPORTANT! Never use this wire to drive anything but a relay or a low-current input! The transis-
torized output can only supply 200 mA of current. Connecting directly to a solenoid, motor, or other
high-current device will cause it to fail.
plug-in LED and valet/program switch
The LED and the Valet/Program switch both plug into the control module. The status LED plugs into the small
two-pin port, while the Valet®/Program switch should be plugged into the larger blue two-pin port. The status
LED and Valet®/Program switch each fit into 9/32-inch holes.

door lock wiring diagrams
This system can control two common power door lock types without any additional parts! To interface with some
vehicles or if an actuator is to be installed, you will need a 451M Door Lock Relay Satellite or two relays.
This security 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,
you must take care to ensure that it is not a Type C direct-wire system.
IMPORTANT! If you mistake a Type C direct-wired system for a Type A positive-pulse system, the
module will be damaged!
Here is a test: Cut the wire which 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 one or more, but not all, motors stop operating, you have cut a wire leading directly to one or more motors.
Reconnect the wire and look for another wire.
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-later), many of the S10 Blazers, the Corvette, '95 Cavalier/Sunfire 1993
and newer, Camaro/Firebird all use Type C door locks, and cannot be controlled without a 451M! Almost all domes-
tically-built Fords are Type C. Ford builds almost no Type A systems. Chrysler builds both Type A and Type C, so
test carefully.

IMPORTANT! Remember that the functions of these wires reverse between Type A and Type B!
This system is common in many Toyotas, Nissans, Hondas and Saturns, as well as Fords with the keyless-entry
systems (some other Fords also use Type B).
The switch will have three wires on it, and one wire will test ground all the time. One wire will pulse (-) when
the switch locks the doors, and the other wire will pulse (-) when the switch unlocks the doors. This type of
system is difficult to mistake for any other type.
IMPORTANT! Remember that the functions of these wires reverse between Type A and Type B!
type B: (-) pulses from the switch to the factory relays

Interfacing with a reversing polarity system requires either two relays or one 451M (not included). It is critical
to identify the proper wires and locate the master switch to interface properly. Locate wires that show voltage
on lock and unlock. Cut one of the suspect wires and check operation of the locks from both switches. If one
switch loses operation in both directions and the other switch operates in one direction only, you have located
one of the target wires. The switch that lost all operation is the master switch. If one switch works both direc-
tions and the other switch works only one direction, you have a Type A system. If both switches still operate,
but one or more doors have stopped responding entirely, you have cut a motor lead. Reconnect it and continue
to test for another wire. Once both wires have been located and the master switch identified, cut both wires and
interface as shown below.
IMPORTANT! If these are not connected properly, you will send (+) 12 Volts directly to (-) ground,
possibly damaging the factory switch.
type C: reversing polarity

In order for this system to control one or more aftermarket actuators, a 451M or two relays (optional) are needed.
Vehicles without factory power door locks require the installation of one actuator per door. This requires mount-
ing the door lock actuator inside the door. Other vehicles may only require one actuator installed in the driver's
door if all door locks are operated when the driver's lock is used. This type of installation is required to operate
factory lock systems in Volvo (except 850), SAAB, and most Mazda, Isuzu and Subaru models.
The fuse used on 12V inputs should be 7.5A per motor installed in the vehicle.
IMPORTANT! Do not connect the outputs of the alarm directly to the actuator!
type D: after-market actuators

16 © 1999 Directed Electronics, Inc. Vista, CA
Door locks are controlled by an electrically activated vacuum pump. Some Mercedes and Audis use a Type D
system. Test by locking doors from the passenger key cylinder. If all the doors lock, the vehicle's door lock system
can be controlled with just two relays (optional). The control wire can be found in either kick panel and will show
(+)12V when doors are unlocked and (-) ground when doors are locked.
To interface see diagram below. The system must be programmed for 3.5 second door lock pulses (see Operating
Settings Learn Routine section of this guide).
Type F door locks usually require a negative pulse to unlock, and cutting of the same wire to lock the door. In
some vehicles, these are reversed. Type F door locks are found in some late-model Nissan Sentras, 240SX, and
1992 and later Nissan 300ZX. They are also found in some Mazda MPV's and some Mitsubishi's.
One relay (optional) is used to interface Type F door locks as follows:
type F: one-wire system
type E: mercedes-benz and audi (1985 & newer)

transmitter/receiver learn routine™
Transmitters are taught to the system using the Learn Routine. This system will learn up to four transmitters.
Both transmitters come factory programmed using Button I for lock, unlock, and panic; Button II for Channel 2
and Silent Mode; and Buttons I and II together operate Channel 3. This configuration can be changed or new
remotes can be added to the system using the Learn Routine. For added security, this Learn Routine can be locked
using the DEI Bitwriter (P/N 998T). If the unit does not respond to the Learn Routine, plug the Bitwriter into
the data port of this unit and verify that the Transmitter Programming is unlocked.
1. Key. Turn the ignition to the run position. (The YELLOW H1/9 wire must be already be con-
nected.)
2. Valet®/Program switch. Press and release the Valet®/Program switch the correct number of
times corresponding to the desired channel number. Then press the Valet/Program switch
once more and HOLD it. The LED will blink to indicate the selected channel and the horn
will honk (if connected). Do not release the Valet/Program switch.
NOTE: Channel Nine of the Transmitter Learn Routine will delete all transmitters that are pro-
grammed into the system as well as change the operating settings back to the default settings (see
Operating Settings Learn Routine section of this guide). To use this option, select Channel 9 (LED
will blink nine times) and then transmit from any button of a known transmitter.
3. Transmit. While holding the Valet®/Program switch, press the button on the transmitter that
you would like to control the selected receiver channel. One honk will confirm that the code
has been learned.
CHANNEL PRESS AND RELEASE
NUMBER THE VALET/PROGRAM SWITCH TO PROGRAM FUNCTION
1 One time Lock/Arm, Unlock/Disarm, Panic
2 Two times Channel 2 output
3 Three times Channel 3 output
4 Four times Lock/Arm, Panic
5 Five times Unlock/Disarm, Channel 2
6 Six times Panic only
7 Seven times Auto Learn OEM Configuration*
8 Eight times Auto Learn Standard Configuration*
9 Nine times Delete all transmitters
* NOTE: For Auto Learn Configurations, see Transmitter Configurations section of this guide.

4. Release. Once the code is learned, the Valet/Program switch can be released.
You can advance from one channel to another by releasing the Valet®/Program switch and tapping it to advance
channels and then holding it. For instance: You have programmed Channel 1 and you want to program Channel
2. Release the Valet®/Program switch. Press it one time and release it to advance from Channel 1 to Channel 2.
Now, press and hold the Valet/Program switch down and the unit will chirp twice. As before, do not release it.
If you want to program Channel 3 after programming Channel 1, release the Valet/Program switch, press it twice
and then release it to advance to Channel 3. Then press the Valet/Program switch once more and hold it. The
horn will honk three times to confirm it is ready to receive the code from the transmitter to program Channel 3.
The learn routine will be exited if:
■The ignition is turned off.
■The Valet/Program switch is pressed too many times.
■More than 15 seconds elapses between steps.
One long horn honk (if connected) indicates that the Learn Routine has been exited.

two vehicle operation with single transmitter
You can get two-vehicle operation with the transmitters that come with the system; however, you will not be
able to use all the auxiliary channels of the system (or all the auxiliary channels of the other system), unless
using a 485T 4-button transmitter.
Here's what to do:
1. Using Learn Routine, program Button I into System One as the arm/disarm button. Do this with all four
remotes.
2. Do the same with System Two, except program Button II of all four remotes as the arm/disarm button.
If using DEI®485T four-button remotes, all auxiliary channels are available on both vehicles. Before program-
ming, make a list of all channels on each vehicle, and decide which button(s) should control which channel.
For example, if you wanted the top two buttons to control Vehicle One and the bottom two buttons to control
Vehicle Two, here is how each system would be programmed:
VEHICLE 2
Button III Lock/Arm, Unlock/Disarm, Panic
Button IV Channel 2
Buttons III and IV Channel 3
VEHICLE 1
Button I Lock/Arm, Unlock/Disarm, Panic
Button II Channel 2
Buttons I and II Channel 3
Button I ......................operates ....................Lock/Arm, Panic
Button II.....................operates ....................Unlock/Disarm, Channel 2
Buttons I and II ...........operate .....................Channel 3

operating settings learn routine™
Many of the operating settings of this unit are programmable. They can be changed whenever necessary through
a computer-based learn routine. To simplify programming, the DEI Bitwriter (P/N 998T) can be used to change
options as well as lock the Learn Routine. If there is no response from the Learn Routine, plug the DEI Bitwriter
into the data port and verify that the Feature Programming is unlocked.
1. Key. Turn the ignition on and then back off. (The H1/9 YELLOW switched ignition input
must be connected.)
2. Choose. Within 10 seconds, press and release the Valet®/Program switch the number of
times corresponding to the feature number you want to program (see the Features Menu
section of this guide). The LED ON settings listed in the Features Menu table are the factory
default settings.
Once the Valet/Program switch has been pressed and released the number of times corre-
sponding to the feature you wish to program, press it once more and hold it. After a
second, the LED will flash to indicate which feature you have accessed. For example, groups
of five flashes would indicate access to Feature 5 (Active/Passive Locking feature). The
horn will also honk five times (if connected).
3. Transmit. The transmitter buttons are used to select the desired feature setting. As
shipped, the unit is configured to the default LED ON settings. Pressing the Channel 1
transmitter button (usually Button I) will program the feature to the LED ON setting. The
LED will light solid (stop flashing) to indicate the setting. The horn will honk once (if con-
nected). Pressing the Channel 2 transmitter button (usually Button II) will change the
setting to the LED OFF setting. The LED will turn off indicating the change and the horn
will honk twice (if connected).
4. Release. The Valet®/Program switch can now be released.
For example to program Feature 1 (Arming Mode) from active to passive, within 10 seconds of turning the igni-
tion off, press and release the Valet®/Program switch once. Then press it again and hold it. The LED will flash in
groups of one and the horn will honk once (if connected). While holding the Valet®/Program switch, press the
Channel 2 transmitter button. The LED will stop flashing and go out. The horn will honk twice if connected.
Passive arming is now programmed. If this is not the desired setting, without releasing the Valet®/Program switch,
press the Channel 1 button on the transmitter. The LED will light solid and the horn will honk once if connected.
Active arming is now programmed. Release the Valet®/Program switch after the desired selection is made.
