H1/1 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.
NOTE: Always use a fuse within 12 inches of the point you obtain (+)12V. Do not use the fuse in
the harness for this purpose. This fuse protects the module itself.
H1/2 BLUE (-) 200 mA Second Unlock Output
The H1/2 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 trans-
mitter. This negative unlock output is used to unlock the passenger doors.

H1/3 BLACK/WHITE-1 Domelight Supervision Input
This wire determines what the output polarity of H1/4 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.
H1/4 BLACK/WHITE Domelight Supervision Output
Connect this wire directly to the domelight circuit in the vehicle. The on-board relay will drive
circuits up to 30 amperes. The polarity of this output is determined by the connection of the input
wire H1/3 in the Relay Harness.
NOTE: If the input wire H1/3 is not connected, there will be no output on this wire.
H1/5 GREEN/BLACK Lock #30 Common (Output)
The system has door lock relays on-board, and can directly interface with most electric power door
lock systems drawing 30 amps or less. It can also drive aftermarket actuators directly. (Some vehicles
require that an aftermarket actuator be added to the driver’s door to allow system control, see Type
D wiring section in Tech Tip Document 1041).
H1/6 WHITE/BLACK Lock #87 Normally Closed
See H1/5.
H1/7 VIOLET/BLACK Lock #87 Normally Opened (Input)
See H1/5.
H1/8 BLUE/BLACK Unlock #30 Common (Output)
See H1/5.
H1/9 VIOLET Unlock #87 Normally Open (Input)
See H1/5.
H1/10 WHITE (+/-) Parking Light Flash Output
This wire provides a high current + or - output to flash the parking lights (+ is factory default
setting). This is suitable for driving (-) light control wires in Toyota, Lexus, BMW, some Mitsubishi,
some Mazda, etc. If the vehicle has a negative parking light circuit, the light flash jumper on the
control module must be moved.
IMPORTANT! The H1/3 wire is not required for wiring the door locks. Depending on
the type of door lock system, there may be additional wires for the Door Lock wiring
that are not required.

H1/11 BLACK (-) Chassis Ground Connection
Connect this wire to a clean, paint-free sheet metal location (driver kick panel) using a factory bolt
that DOES NOT have any vehicle component grounds attached to it. A screw should only be used
when in conjunction with a two-sided lock washer. Under dash brackets and door sheet metal are
not acceptable ground points. It is recommended that all security components be grounded at the
same location.
H1/12 BROWN (-) Horn Honk Output
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 optional relay can be used to interface with the system, as shown below.
H1/13 LT. GREEN/BLACK Factory Alarm Disarm
This wire supplies a
H1/14 WHITE/BLUE (-) Channel 3 Output
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
Directed’s 551T Valet®Start system, 529T or 530T power window controllers, etc.
IMPORTANT! Never use this wire to drive anything but 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.

H1/15 YELLOW (+) Switched Ignition Input
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).
H1/16 ORANGE (-) 500mA Ground-When Armed Output
This wire supplies a (-) 500mA ground as long as the system is armed. This output ceases as soon
as the system is disarmed.
Note: If using the H1/16 Orange wire to activate an add-on accessory such as window automation,
pager or voice module a 1-Amp diode must be installed to ensure proper operation. Insert the diode
as shown the the following diagram.
H1/17 BROWN/BLACK Unlock #87A Normally Closed
See H1/5.
H1/18 RED/WHITE channel 2, 200mA (-) 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.

Peripheral Plug-In Harnesses
Super Bright LED, 2-Pin WHITE Plug
The super bright LED operates at (+) 2 volt DC and plugs into the two-pin WHITE port. Make
sure the LED wires are not shorted to ground as the LED will be damaged. Multiple LED’s can be
used, but they must be wired in series. The LED fits into a 9/32-inch mounting hole. Be sure to
check for clearance prior to drilling the mounting hole.
NOTE: Never use a BLUE LED in combination with a RED LED.
DIA-41
IMPORTANT! Never use this wire to drive anything but a relay or a low-current input!
The transistorized output can only supply 200 mA of current. Connecting directly to a
solenoid, motor, or other high-current device will cause it to fail.

Valet/Program Switch, 2-Pin BLUE Plug
The Valet/Program button should be accessible from the driver’s seat. It plugs into the BLUE port
on the side of the unit. Consider how the button will be used before choosing a mounting location.
Check for rear clearance before drilling a 9/32-inch hole and mounting the button.
System Features Learn Routine
The System Features Learn Routine dictates how the unit operates. It is possible to access and
change any of the feature settings using the Valet®/Program switch.
TTooeenntteerrtthheelleeaarrnnrroouuttiinnee::
1. KKeeyy..Turn the ignition on and then back off.
2. CChhoooossee..Within 10 seconds, press and release the Valet®/Program switch
the number of times corresponding to the feature number you want to
program. (See Feature Menus.) Once the Valet®/Program switch has been
pressed and released the desired number of times, press it once more and
hold it. After a second, the LED will flash and the horn will honk to
indicate which feature you have accessed.
3. TTrraannssmmiitt..The transmitter is used to select the desired setting. As shipped,
the unit is configured to the LED ON settings. These are the default
settings. Pressing the lock button will set it to the LED ON setting. The
LED will light solid (stop flashing) to indicate the setting. The horn will
honk once (if connected). Pressing the unlock button will change the
setting to the LED OFF setting. The LED will go out 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 the arming mode from active to passive, within 10 seconds of turning the
ignition off, and 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 unlock button. The LED will stop flashing and go out. The horn
will honk twice if connected. Passive arming is now programmed. If that was not the desired setting,
without releasing the Valet®/Program switch, press the lock button. 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 selection has been made.
You can advance from feature to feature by pressing and releasing the Valet®/Program switch the
number of times necessary to get from the feature you just programmed to the feature you wish to
access. For example, if you just programmed Feature 2 and you next want to program Feature 3 to
off, release the Valet®/Program switch. Press and release it once to advance from Feature 2 to Feature
3. Then press it once more and hold it. The LED will flash in groups of three and the horn will
honk three times (if connected) to confirm that you have accessed Feature 3.
The learn routine will be exited if:
➤ The ignition is turned on.
➤ The Valet/Program switch is pressed too many times.
➤ More than 15 seconds elapses between programming steps.
One long horn honk (if connected) indicates that the Learn Routine has been exited.
