Warning! Safety first
The following safety warnings must be observed at all times:
Due to the complexity of this system, installation of this product must only be•
performed by an authorized Directed Electronics dealer.
When properly installed, this system can start the vehicle via a command•
signal from the remote control. Therefore, never operate the system in an
area that does not have adequate ventilation.
The following precautions are the sole responsibility of the user; however, autho-
rized Directed Electronics dealers should:
Never use a test light or logic probe when installing this•
unit. Always use a multimeter.
Never operate the system in an enclosed or partially enclosed area without•
ventilation (such as a garage).
When parking in an enclosed or partially enclosed area or when having•
the vehicle serviced, the remote start system must be disabled using the
installed toggle switch. It is the user’s sole responsibility to properly handle
and keep out of reach from children all remote controls to assure that the
system does not unintentionally remote start the vehicle.
USER MUST INSTALL A CARBON MONOXIDE DETECTOR
IN OR ABOUT THE LIVING AREA ADJACENT TO THE VE-
HICLE. ALL DOORS LEADING FROM ADJACENT LIVING AR-
EAS TO THE ENCLOSED OR PARTIALLY ENCLOSED VEHICLE
STORAGE AREA MUST REMAIN CLOSED AT ALL TIMES.
Use of this product in a manner contrary to its intended mode of operation may
result in property damage, personal injury, or death. Except when performing
the Safety Check outlined in this installation guide, (1) Never remotely start the
vehicle with the vehicle in gear, and (2) Never remotely start the vehicle with the
keys in the ignition. The user will be responsible for having the neutral safety fea-
ture of the vehicle periodically checked, wherein the vehicle must not remotely
start while the car is in gear. This testing should be performed by an authorized
Directed Electronics dealer in accordance with the Safety Check outlined in
this product installation guide. If the vehicle starts in gear, cease remote start
operation immediately and consult with the user to fix the problem immediately.

6© 2008 Directed Electronics. All rights reserved.
After the remote start module has been installed, test the remote start module
in accordance with the Safety Check outlined in this installation guide. If the
vehicle starts when performing the Neutral Safety Shutdown Circuit test, the
remote start unit has not been properly installed. The remote start module must
be removed or properly reinstalled so that the vehicle does not start in gear. All
installations must be performed by an authorized Directed Electronics dealer.
OPERATION OF THE REMOTE START MODULE IF THE VEHICLE STARTS IN
GEAR IS CONTRARY TO ITS INTENDED MODE OF OPERATION. OPERAT-
ING THE REMOTE START SYSTEM UNDER THESE CONDITIONS MAY RE-
SULT IN PROPERTY DAMAGE OR PERSONAL INJURY. IMMEDIATELY CEASE

Installation points to remember
This product is designed for fuel-injected, automatic transmission vehicles only.
Installing it in a standard transmission vehicle is dangerous and is contrary to
its intended use.
➤ Virtual tach
Virtual Tach is a new feature for Directed this year. It is the default RPM-sensing
method for the new Responder LE hybrid keyless entry /remote start systems.
Virtual Tach gives the installer the performance of a hard wired tach wire, with
the convenience of voltage sensing. It is far superior to any voltage-sense feature
you’ve tried before.
Virtual Tach monitors the cranking voltage of the vehicle using a very fast micro
controller and an analog-to-digital converter. The microprocessor “saves” the
base voltage as a reference. When Virtual Tach “sees” the slightest uptick in
voltage, indicating that the alternator is charging the battery, the starter motor
shuts off instantly.
➤ D2D
The system has the ability to interface with an XK module through the D2D port.
The advantage to using a D2D interface is that there is less wiring involved in
the installation. Check the XK module installation guide to determine which wires
are not needed, and which options are available.

8© 2008 Directed Electronics. All rights reserved.
➤ Before beginning the installation
Please read this entire installation guide before beginning the installation.•
The installation of this remote start system requires interfacing with many of
the vehicle’s systems. Many new vehicles use low-voltage or multiplexed
systems that can be damaged by low resistance testing devices, such as
test lights and logic probes (computer safe test lights). Test all circuits with a
high quality digital multi-meter before making connections.
Do not disconnect the battery if the vehicle has an anti-theft-coded radio.•
If equipped with an air bag, avoid disconnecting the battery if possible.
Many airbag systems display a diagnostic code through the warning lights
after the lights lose power. Disconnecting the battery causes the anti-theft
code to be erased, which can then require a trip to the dealer.
If using an external LED or Valet Switch, check with the customer about•
where to locate the switch.
To avoid accidental battery drainage; turn off the interior lights or remove•
the dome light fuse.
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.
When testing, don’t forget that this system is equipped with Nuisance•
Prevention® Circuitry (NPC). NPC can bypass trigger zones, making
them appear to stop working. See the Nuisance Prevention® Circuitry
section of the Owner's Guide.
Review and complete the Safety Check section of this guide prior to the•
vehicle reassembly.

Component locations and finding wires
For detailed information on where to locate components, and how to find the
wires you need, please refer to the Direct Tech web site at www.directechs.
com.
➤Valet/program switch
IMPORTANT! When the vehicle is delivered, please show the user where this
switch is located and how to disarm the system with it.
Ensure that the location you pick for the switch has sufficient clearance to the
rear. The switch should be well hidden. It should be placed so passengers or
stored items (such as in a glove box or center console) cannot accidentally hit it.
The switch fits into a 9/32-inch hole.
This system has Remote Valet. The user can enter and exit Valet Mode without
having to reach the Valet/Program switch. This feature was introduced so that
switch location was less critical in day-to-day use. As long as the Valet/Program
switch can be reached to disarm without a transmitter, easy access is not im-
portant.

10 © 2008 Directed Electronics. All rights reserved.
➤Status LED
Things to remember when positioning the Status LED:
It should be visible from both sides and the rear of the vehicle, if pos-•
sible.
It needs at least 1/2-inch clearance to the rear.•
It is easiest to remove a small panel, such as a switch blank or a dash•
bezel, before drilling a 9/32-inch hole.
Use quick-disconnects near the LED wires if the panel is removable. This lets•
mechanics or other installers remove the panel without cutting the wires.

Making your wiring connections
Before making your connections, plan how your wires will be routed through
the vehicle. For instance, the red 12V constant input and the remote start igni-
tion wires are often routed together to the ignition switch harness. In order to
keep the wiring neat and make it harder to find, you may wish to wrap these
wires together in electrical tape or conceal them in tubing similar to what the
manufacturer used.
There are two acceptable ways of making a wire connection - solder connec-
tions and crimp connectors. When properly performed, either type of connection
is reliable and trouble-free. Regardless of whether you solder your connections
or you use mechanical type crimp-on connections, ensure that all connections
are mechanically sound and that they are insulated, especially when connecting
data lines in the vehicle.
Cheap electrical tape, especially when poorly applied, is not a reliable insu-
lator. It often falls off in hot weather. Use good quality electrical tape or heat
shrink.
Never twist-and-tape the wires together without soldering.•
Never use “fuse taps”, as they can damage fuse box terminals.•
If you use tapping connectors such as T-Taps (not to be confused with Scotch-
Locks), avoid using them in higher-current applications (constant 12V, ground,
etc.) These connectors are inferior in quality and should be avoided.

H1/1 RED/WHITE (-) 200mA TRUNK RELEASE, 200 mA (-) output
When the system receives the code controlling trunk release output for longer
than 1.5 seconds, the red/white wire will supply output as long as the transmis-
sion continues. This is typically used to operate a trunk/hatch release or other
relay-driven function.
Warning! Never use this wire to drive anything but
a relay or a low-current input, supplied output is only
200mA. Connecting directly to a solenoid, motor, or
other high-current device will cause the module to fail.

H1/2 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 15A fuse in the harness for this purpose. This fuse protects the module.
H1/3 BROWN (+) SIREN OUTPUT
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 connected the control module’s
black ground wire. See Features Description section for horn output.

16 © 2008 Directed Electronics. All rights reserved.
H1/5 BLACK (-) CHASSIS GROUND
Remove any paint and 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 including the siren to the same
point in the vehicle.
H1/6 VIOLET (+) DOOR TRIGGER INPUT, ZONE 3
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. This wire reports Zone 3.

17
© 2008 Directed Electronics. All rights reserved.
H1/7 BLUE (-) MULTIPLEX INPUT, ZONE 4
Inputs shorter than 0.8 seconds will trigger the Warn Away response, while in-
puts longer than 0.8 seconds will trigger the full alarm sequence. If installing an
optional Directed Electronics dual stage sensor, connect both the blue and the
green wires of the optional sensor to this input. This wire will report Zone 4.
H1/8 GREEN (-) DOOR TRIGGER INPUT, ZONE 3
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 dome light circuit, there is usually a wire that is unaffected by the
delay circuitry. This wire reports Zone 3.

18 © 2008 Directed Electronics. All rights reserved.
H1/9 BLACK/WHITE (-) 200mA DOME LIGHT OUTPUT SUPERVISION OUTPUT
Connect this wire to the optional dome light supervision relay as shown below:
Important! This output is only intended to drive a relay. It cannot be connected
directly to the dome light circuit, as the output cannot support the current draw
of one or more light bulbs.
H1/10 WHITE/BLUE REMOTE START (-) ACTIVATION INPUT
This input comes from the factory set to 1 activation pulse. This means that it is
necessary to have a two consecutive on ground pulse on the white/blue wire for
the remote start to activate or to deactivate. The same holds true for the remote
control activation it is necessary to press the button once for the remote start
to activate or deactivate.
Note : The number of activation inputs can be programmed to 1 or 2 pulses with
an optional momentary switch. This setting affects both the input wire and the
remote control when operating the remote starter.

section of this guide.) P/N 8617 or a standard automotive SPDT relay must be
used on the H1/11 light flash output harness wire.
H1/12 ORANGE (-) 500mA GROUND WHEN ARMED OUTPUT
This wire supplies a (-)500 mA ground as long as the system is armed. The out-
put ceases as soon as the system is disarmed. The orange wire may be wired
to an optional Directed Electronics 8618 starter kill relay.

➤Auxiliary harness (H2), 6-pin connector
H2/1 LIGHT BLUE 200mA (-) 2nd UNLOCK OUTPUT
This wire produces a (-) 200mA output for progressive locks in which the driver
door unlocks first and the remaining locks unlock with a second press of the
unlock button.
H2/2 WHITE/BLACK 200mA PROGRAMMABLE (-) AUX 2 OUTPUT
This wire provides 200 mA programmable output whenever the transmitter
button(s) controlling Aux 3 is pressed. This output can be programmed to provide
the following types of outputs
Validity: Output that sends a signal as long as the transmission is re-•
ceived.
Latched: Output that sends a signal when the Aux channel button is pressed•
and continues until the same button is pressed.
Latched, reset with ignition: Similar to the latched output, this type of output•
turns On the first time the Aux channel button is pressed, and turns Off the
next time the same button is pressed. This type of output additionally stops
and resets whenever the ignition is turned On and then Off.
30 seconds (60, 90) timed: The output sends a continuous signal for 30•
seconds.
Note: Bitwriter® programs from 1 to 90 seconds.
Warning! Never use this wire to drive anything
but a relay or a low-current input, supplied out-
put is only 200mA. Connecting directly to a
solenoid, motor, or other high-current device
will cause the module to fail.
