This wire is a low current output to a relay for the horn to sound when the system has been triggered.
It can be programmed to either pulse or latch on when the alarm is triggered.
H1/9 WHITE/BLUE 200 mA (-) channel output 3
This wire provides a (-) 200 mA output whenever the transmitter button(s) controlling Channel 3
is pressed. This output can be programmed to provide the following types of output (see
System
Features Learn Routine
section of this guide):
➤➤A vvaalliiddiittyyoutput will send a signal as long as the transmission is received.
➤➤A llaattcchheeddoutput will send a signal continuously when the Channel 3 button(s) is pressed and
released. The signal will continue until channel three is pressed again.
➤➤A llaattcchheedd//rreesseettwwiitthhiiggnniittiioonnoutput works similar to the latched output, but will also reset
(output will stop) when the ignition is turned on and then off.
➤➤A 3300((6600,,9900))sseeccoonnddttiimmeeddoutput will send a signal for 30 seconds when Channel 3 is pressed.
This output can be turned off during the 30-second period by pressing Channel 3 again. The

H1/11 and H1/12 White indicator light flash outputs
These wires are the output of an on-board dual make relay and should be connected to wires in the
vehicle that control the indicators. If the vehicle’s indicator lights are controlled by a single wire,
connect both WHITE wires to this single wire.
H1/13 BLACK/WHITE 2 Interior Light Illumination Output (30)
Connect this wire to the interior light circuit trigger wire or the alarm’s door trigger input wire H1/3
or H1/6. When the alarm is disarmed this wire will provide an output to turn on the interior light
for 30 seconds.
H1/14 BLACK/WHITE 1 (+) or (-) Interior Light Illumination Input (87)
This wire determines the output of the BLACK/WHITE H1/13 wire. If the vehicle has a negative
switched interior light circuit, ground this wire; if the vehicle has a positive switched interior light
circuit, attach this wire (using a fuse) to a 12 volt constant source.
H1/15 RED/WHITE (-) channel 2 (200mA)
This wire produces a 200mA output when activated by the remote control and can be used to
operate a variety of accessories. This is often used to operate a boot/hatch release or other relay-
driven function. All accessory outputs can be programmed to different types of outputs. Please see
Programming Note #5.

Identifying the Door Lock System
There are eight different types of common door lock circuits found in vehicles (some vehicles use
more unusual systems). The eight most common systems are:
➤➤Type A: Three-wire (+) pulse controlling factory lock relays.
➤➤Type B: Three-wire (-) pulse controlling factory lock relays.
➤➤Type C: Direct-wired reversing-polarity switches. The switches are wired directly to the motors.
This type of door lock system has no factory relays.
➤➤Type D: Aftermarket door servo driven systems. These include slave systems without an actuator
in the driver’s door but with factory actuators in all the other doors. These can be controlled
with the installation of an aftermarket motor in the driver’s door.
➤➤Type E: Electronically-activated vacuum systems. This may require special programming of the
system.
➤➤Type F: One-wire system.
➤➤Type G: Positive (+) multiplex resistor-based circuit.
➤➤Type H: Negative (-) multiplex resistor-based circuit.

14

Type A: Positive-Triggered, Relay-Driven System
The system can control Type A door locks directly, with no additional parts. The switch will have
three wires on it; one will test (+)12 volt constantly. The others will alternately pulse (+)12 volt
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 (+)12 volt alternately on lock
and unlock, make sure that it is not a Type C direct-wire system.
Cut the wire that pulses (+)12 volt on lock, and then operate the switch to unlock.
➤➤If all doors unlock, the vehicle uses 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 instead find the actual
wires leading to the switch.
NOTE: Some BMW and VW vehicles will require the door lock output pulse to be
programmed (Menu 1, Feature 7) to 0.4 secs or the windows will either open or close
slightly when arming and disarming.

Type B: Negative-Triggered, Relay-Driven System
This system is common in many Toyotas, Nissans, Hondas and most European Ford vehicles.
The switch will have three wires on it, and one wire will test ground all the time. One wire will pulse
negative (-) when the switch locks the doors, and the other wire will pulse negative (-) when the
switch unlocks the doors. This type of system is difficult to mistake for any other type.

Type C: Reversing Polarity System
Use these instructions if the door lock motor/switch has four or five heavy-gauge wires. This type
of switch has two outputs that rest at (-) ground.
It is critical to identify the proper wires and locate the master switch to interface properly. Locate
wires that show voltage when the switch is moved to the lock or unlock position. Cut one of the
suspect wires and check operation of the locks from both switches. If one switch loses all operation
in both directions then you have cut one of the correct wires and the switch that is entirely dead is
the master switch. If both switches still operate in any way and one or more door motors 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 described in the following paragraphs.
➤➤WHITE/BLACK: Once both door lock wires are located and cut, connect the white/black wire
to the master switch side of the lock wire. The master switch side will show (+)12V when
activated and (-) ground at rest.
➤➤GREEN/BLACK: Connect the green/black wire to the motor side of the lock wire.
➤➤VIOLET/BLACK and H2/4 VIOLET: These wires must be connected to constant (+)12 volts
(via a 15-amp fuse). The best connection point for these wires is directly to the positive (+)
battery post or an unfused source at the vehicle fusebox.
➤➤BLUE/BLACK: Connect the blue/black wire to the motor side of the unlock wire.
➤➤BROWN/BLACK: Connect the brown/black wire to the master switch side of the unlock wire.
The master switch side will show (+)12V when activated and (-) ground at rest.
WARNING! If these wires are not connected properly, you will send (+)12V directly to
(-) ground, possibly damaging the alarm or the factory switch.
IMPORTANT! To interface with these systems, you must cut two switch leads. The relays
must duplicate the factory door lock switches’ operation. The master switch will have one
or two ground inputs, one (+)12V input, and two switch outputs going directly to the slave
switch and through to the motors. These outputs rest at (-) ground. The lock or unlock
wire is switched to (+)12V, while the other wire is still grounded, thus completing the
circuit and powering the motor. This will disconnect the switch from the motor before
supplying the motor with (+)12V, avoiding sending (+)12V directly to (- ) ground.

Type D: After-Market Actuators
Vehicles without central door locking or with single-point central locking only require additional
door motors. This requires mounting the door lock actuator inside the door. Some 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.
The fuse used on 12 volt inputs should be 7.5A per motor installed in the vehicle.
Type E: Mercedes-Benz and Audi (1985 and newer)
Type E door locks are controlled by an electrically activated vacuum pump. Test by locking doors
from the passenger key cylinder. If all the doors lock, the vehicle's door lock system can be wired as
type E. The control wire can be found in either kick panel and will show (+)12 volt 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
up to 1993 and 1 second pulse 1994 or newer.

In some vehicles, these functions are reversed. These door locks are found most commonly in
Mitsubishi, Proton and Lotus.

Type G: Positive (+) Multiplex
SSiinnggllee--RReessiissttoorrTTyyppee
If one resistor is used in the door lock switch/key cylinder, the wire will pulse (+)12V in one
direction and less than (+)12V when operated in the opposite direction.
TTwwoo--RReessiissttoorrTTyyppee
If two resistors are used in the factory door lock switch/key cylinder, the switch/key cylinder will
read less than (+)12V in both directions.

To determine the resistor values, the door lock switch/key cylinder must be isolated from the factory
door lock system. For testing, use a calibrated digital multimeter that is set to ohms.
1. Cut the output wire from the door lock switch/key cylinder in half.
2. Test with the meter from the switch side of the cut door lock switch/key cylinder wire to a
reliable constant (+)12V source. Some good constant (+)12V references are the power input
source to the door lock switch/key cylinder, the ignition switch power wire, or the (+) terminal
of the battery.
3. Operate the door lock switch/key cylinder in both directions to determine the resistor values.
If the multimeter displays zero resistance in one direction, no resistor is needed for that
direction.
4. Once the resistor value(s) is determined, refer to the wiring diagram for proper wiring.
IMPORTANT! To ensure an accurate resistance reading, do not touch the resistor or
leads during testing.
