Installation Points to Remember
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 will display a diagnostic
code through their warning lights after they lose power. Disconnecting the battery requires this
code to be erased, which can require a trip to the dealer.
➤ Check with the customer on integrated LED/Valet®switch location.
➤ Remove the domelight fuse. This prevents accidentally draining the battery.
➤ Roll down a window to avoid being locked out of the car.
Finding the Tachometer Wire
To test for a tachometer wire, a multimeter capable of testing AC voltage must be used. The
tachometer wire will show between 1V and 6V AC. In multi-coil ignition systems, the system can
learn individual coil wires. Individual coil wires in a multi-coil ignition system will register lower
amounts of AC voltage. Also, if necessary, the system can use a fuel injector control wire for engine
speed sensing.
Common locations for a tachometer wire are the ignition coil, instrument cluster, fuel injectors, or
engine computers.
IMPORTANT! 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.

6©2003
Directed Electronics, Inc.
How to find a tachometer wire with your multimeter:
1. Set to ACV or AC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Start and run the vehicle.
4. Probe the wire you suspect of being the tachometer wire with the red probe of the meter.
5. If this is the correct wire the meter will read between 1V and 6V.
Finding the WAIT-TO-START Bulb Wire for Diesels
In diesel vehicles it is necessary to interface with the wire that turns on the WAIT TO START light
in the dashboard. This wire illuminates the bulb until the vehicle’s glow plugs are properly heated.
When the light goes out the vehicle can be started. This wire is always available at the connector
leading to the bulb in the dashboard. It can also be found at the Engine Control Module (ECM)
in many vehicles.
To test and determine the polarity of this wire:
1. Set your multimeter to DCV or DC voltage (12 or 20V is fine).
2. Attach the (+) probe of the meter to (+)12V.
3. Probe the wire that you suspect leads to the bulb with the (-) probe of the meter.
4. Turn the ignition switch to the ON position.
5. If the meter indicates 12 volts until the light goes out you have isolated the correct wire and the
wire's polarity is negative (ground while the bulb is on).
6. If the meter reads zero volts until the light goes out and then reads 12 volts, you have isolated
the correct wire and the wire's polarity is positive.
After the Installation
➤ Test all functions. The Using Your System section of the Owner's Guide is very helpful when
testing.
➤ Review and complete the Safety Check section of this guide prior to the vehicle reassembly.
Vehicle Anti-Theft Systems (Immobilizers)
Vehicle anti-theft systems (immobilizers) require a bypass module. The bypass module allows for
easy interfacing, while still maintaining the OEM security system’s integrity. For vehicle listings and
IMPORTANT! Do not test tachometer wires using a test light or logic probe! This will
damage the vehicle.

H1/11 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 itself.
H1/12 RED/WHITE (-) 200 mA output
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.
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.

H2/3 VIOLET/BLACK 200 mA (-) channel 4 output
This wire provides a (-) 200mA output whenever the transmitter button(s) controlling Channel 4
is pressed. This output can be programmed to provide the following types of outputs. (See the
Feature Menus section.)
➤ Validity: Output that will send a signal as long as the transmission is received.
➤ Latched: Output that will send a signal when the Channel 4 button(s) is pressed and will
continue until the same button(s) is pressed again.
➤ Latched, reset with ignition: Similar to the latched output, this type of output turns on the first
time the Channel 4 button(s) 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-second timed: Output that will send a continuous signal for 30 seconds.
➤ Second unlock output: This output can also be programmed to provide a second unlock pulse
whenever the disarm button is pressed within 15 seconds after disarming the system. This

(RPMs). It can be connected to the negative side of the coil in vehicles with conventional coils. In
multi-coil and high energy ignition systems locating a proper signal may be more difficult. (See
Installation Points to Remember section of this guide for finding the tachometer wire.) Once
connected, you must teach the system the tach signal. (See Tach Learning section of this guide.)
H3/6 BLACK/WHITE Neutral Safety Switch Input
Connect this wire to the toggle (override) switch as shown in Figure A. Connect the other wire from
the toggle switch to the park/neutral switch in the vehicle. This wire will test ground with the gear
selector either in PARK or NEUTRAL. This will prevent the vehicle from accidentally being started
while in a drive gear. This input MUST rest at ground in order for the remote start system to
operate. Connected properly the vehicle will only start while in PARK or NEUTRAL.
In some vehicles, the park/neutral position switch activates a factory starter lock out that will not
allow the starter to operate in a drive gear. In these vehicles, connect this wire to the toggle switch
as shown in Figure B. Connect the other wire from the toggle switch to chassis ground.

Neutral Safety Switch Interface
Some vehicles combine the column shift mechanism and the mechanical neutral safety switch into
one mechanical part. In these vehicles, it is impossible to interface the remote start system before
the neutral safety switch. With this type of vehicle, if the vehicle is left in a drive gear and the remote
start system is activated, the vehicle will move and may cause damage to persons or property. The
following test must be performed before the vehicle is released to the customer.
NOTE: You must complete the remote start system installation before doing the following test.
Ensure that the remote start system is functioning normally. This includes connecting to the brake
as a shut-down.
Testing the Neutral Safety Switch
1. Make sure there is adequate clearance to the front and rear of the vehicle because it may move
slightly.
2. Make sure the hood is closed and there are no remote start shut-downs active.
3. Set the emergency brake.
4. Turn the key to the "run" position, this will release the shifter.
5. Place the car in drive (D).
6. Place your foot directly over the brake pedal, but do not depress it. Be ready to step on the brake
if the starter engages.
7. Activate the remote start system.
8. If the starter engages, immediately depress the brake to shut the remote start system down. If
the starter does not engage, no additional safety system is required.
If the starter engages while testing, refer to technical document #1008 (Neutral Safety Update). It
is available to authorized dealers only from the technical resources listed at the beginning of this
manual.
IMPORTANT! Once the interface is complete, attempt to remote start the vehicle with
the door closed and the key in the ignition. The vehicle should not start. If it does,
recheck the connections.

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
5/16-inch mounting hole. Be sure to check for clearance prior to drilling the mounting hole.

Switch, 2-Pin BLUE Plug
The integrated LED/Valet®switch should be accessible from the driver’s seat. It plugs into the BLUE
port on the side of the unit. Since the system features Valet®by using the remote transmitter, the
button can be well hidden. Consider how the button will be used before choosing a mounting
location. The GRAY wire in the two-pin plug may also be used as a (+) Ghost Switch®input and can
be connected to any (+) switch in the vehicle. (See Feature Descriptions section of this guide.)
Programmer Interface, 3-Pin Port
The BLACK three-pin port is provided for programming of the unit. When using the 998T
Bitwriter®, it is possible to configure any and all of the programmable functions. For more
information please refer to the guide packaged with the programmer. This port can also be used to
interface with Directed Video components for on-screen security system programming and trigger infor-
mation.
Shock Sensor Harness, 4-Pin Connector
GREEN (-) multiplex input, zone 2
Inputs shorter than 0.8 seconds will trigger the Warn Away® response, while inputs longer than 0.8
seconds will trigger full alarm sequence and report Zone Two. If installing an optional Directed
dual-stage sensor, connect to the green wire as shown below. The diagram below eliminates the need
for diodes to isolate the sensors.
