Main harness (H1) connections
Factory alarm disarm
H1/1 LIGHT GREEN BLACK (-) 200mA FACTORY ALARM DISARM
Since many newer vehicles come equipped with a factory alarm, it is necessary to disarm it when unlocking
the doors or during remote start. Do not mistake a factory alarm with an immobilizer system. They each
require different disarm operations.
Locate the factory alarm disarm wire following instructions available on www.readyremote.com. Once
the suspect wire is located, place the multi-meter's red lead to a (+)12 volt constant source and secure it.
Put the multi-meter in the DC position. Then probe the suspect wire with the black lead of your meter. While
probing the wire, place the key in the driver's door cylinder. Turn it to the unlock position and hold it when
testing for the disarm wire. The multimeter should read 12V and will go back to 0V when the key is released.
When the correct wire has been found, solder the LIGHT GREEN/BLACK wire of the 9-pin harness to the
wire that you determined to be the factory alarm disarm wire. After this wire has been connected, wrap the
connection with electrical tape.
Some vehicles use a (+) trigger factory alarm system. Use the website resource to determine if your vehicle has
a (+) trigger. If your vehicle has such a system, call 1-800-477-1382 for live technical assistance,
as special wiring and an additional relay is required.
H1/2 GREEN/WHITE (-) 200mA FACTORY ALARM REARM
This wire sends a negative pulse every time the remote start shuts down or the doors are locked. This can be
used to pulse the arm wire of the vehicle’s factory anti-theft device.
H1/3 EMPTY NOT USED
H1/4 WHITE/BLUE (-) ACTIVATION INPUT
This wire allows you to activate the Ready Remote via a pre-existing alarm or keyless-entry system. Two (-)
pulses to this wire will activate remote start.

Ground wire
H1/8 BLACK GROUND
The BLACK wire connects to the pin next to the light flash jumper fuse. First strip back a ¾-inch section of the
insulation off the BLACK wire and crimp a ring terminal (not provided) to that wire. Locate a clean, paint-free
metal surface in the drivers kick panel (DO NOT GROUND ON DASH). Using a self-tapping screw, drill the
screw with the ring terminal to the kick panel. Once screwed down, pull on the wire to ensure a good con-
nection.

Parking light flash
H1/9 WHITE (+/-) LIGHT FLASH OUTPUT
There are several different types of parking light circuits. The following description is for a standard positive-
triggered parking light circuit only. If the web vehicle information suggests a (-) parking light circuit, the fuse
jumper (on the side of the module) must be moved to the opposite position.
Using the web information on the vehicle, locate the suspected wire. Connect the black multimeter lead to
ground in the kick panel. Probe the suspected wire with the red lead of your meter. With the switch in the off
position the multimeter should read 0 volts. While watching the multimeter, turn your headlight switch to the
parking light position. The multimeter should read 12 volts.
While testing the suspected wire, run the dash dimmer light control up and down. The voltage should NOT
vary. If the voltage does vary, then this is the wrong wire. Continue probing to find the correct wire.
Once you have identified the correct wire, solder the small ORANGE wire of the 6-pin harness to it and wrap
the connection with electrical tape. If your light circuit tests the opposite position, you most likely have a (-)
parking light circuit.

Heavy gauge relay harness (H2)
Testing for Ignition Wires
H2/1 PINK OUTPUT TO PRIMARY IGNITION CIRCUIT, 30A (+)
With the multimeter lead still connected in the kick panel, locate the suspected ignition wire. It will test differ-
ently than constant 12 volts. Place the red lead of the multimeter on the suspected wire. With the key in the
off position the multimeter will read 0. Turn the key to the on position and the multimeter will read 12 volts.
Now, watching your multimeter, turn the key to the crank position. If the 12 volts stays on, then you have found
your ignition wire. If the wire tests correctly, solder the PINK heavy gauge wire to it and wrap the connection
with electrical tape.
If the vehicle requires more than one ignition as per the information found at www.readyremote.com,
follow the same test procedure and solder the PINK/WHITE (H2/5) heavy gauge wire to it then wrap the
connection with electrical tape. If your vehicle has only one ignition wire, secure the PINK/WHITE wire and
dress it out of the way.
If your vehicle requires more than two ignitions, an additional relay (not provided) is required. Refer to the
diagram below.

Accessory and starter Wires
H2/2 PURPLE OUTPUT TO STARTER CIRCUIT, 30A (+)
H2/3 ORANGE OUTPUT TO ACCESSORY CIRCUIT, 30A (+)
The starter and accessory wires will be located in the same harness as the ignition and constant power.
To find the accessory wire, leave the multimeter’s black lead connected to ground. Take the red lead and
probe the wire suspected to be the accessory wire. With the key off, your multimeter should read 0 volts.
Turn the key to the on position The multimeter should read 12 volts. Now turn the key to the crank position.
If you have the correct accessory wire, the multimeter will read 0 volts while the starter is cranking, and 12
volts once the key returns to the on position. If the wire tests correctly, strip some insulation off and solder the
ORANGE heavy gauge wire and wrap it with electrical tape.
If your vehicle requires more than one accessory and the PINK/WHITE wire is not being used for 2nd ignition,
you can program the PINK/WHITE to be a 2nd accessory output. This setting may be found in the Feature
Menu, Feature # 6.
If the PINK/WHITE wire is being used for Ignition 2, an additional relay (not provided) is required for a 2nd
accessory. Refer to the diagram below.

Now that the accessories have been located, find the suspected starter wire according to the web informa-
tion. Leave the black lead of your tester on ground and place the red lead of your multimeter on this wire.
The multimeter should read 0 volts in all key positions except the crank position. In the crank position your
multimeter should read 12 volts, and will go to 0 volts when the starter disengages.
Many Nissan and Toyota vehicles have two starter wires. A relay and/or resistor (not provided) is required
to hook up the additional starter wire. Refer to the diagram below.

Important! Always check www.readyremote.com
for information on your vehicle for warnings regarding
the starter wire and engine lights. Some vehicles will trip
a check engine light if the starter wire is cut.
Once you locate the starter wire, cut the wire in half (check the web information before cutting) and try to
start the vehicle. If the vehicle does not start, the correct wire has been identified. Reconnect both ends of
the starter wire while soldering the thick PURPLE H2/2 wire of the heavy gauge wires to it and wrap the con-
nection with electrical tape.
Ignition Output wire
The PINK wire should be the ONLY ignition output to an existing aftermarket alarm system. This wire will
prevent the host system from sensing that the ignition is on during remote start operation.

H2/6 RED (+) 30A HIGH CURRENT 12V INPUT
Constant Power and Ignition Wires
Almost all your power and ignition wires can be found behind the key cylinder under the lower driver's side
dash panel. Using the appropriate hand tools, remove the lower dash panel taking care not to break any
parts. If the panel does not come off easily, check for any additional screws you may have missed.
Once the lower dash panel has been removed, locate the ignition harness at the back of the key cylinder. This
is usually a group of heavy gauge wires (approximate 14ga.).
Place the black lead of the LED tester to a clean metal surface in the kick panel area and secure it. Probe one
of the thicker gauge wires. The ignition wire colors of your specific vehicle can be obtained at
www.readyremote.com.
Important: More problems are attributed to poor ground connections
than any other cause. Take extra care to ensure the ground is a
clean metal-to-metal contact and secure.
Testing for Constant Power Wires
Warning! Before making any connection to constant battery power,
make sure that the two 30 amp fuses are removed from the fuse hold-
ers on the two pink 12 VOLT wires. Failure to do so may cause fire or
shorting of sensitive electrical components.
With the key in the off position, test the suspect wire. The constant power wire will read 12V on the multimeter.
Once the constant power wire has been identified, solder the two heavy gauge 12 VOLT wires RED from the
control module to it and wrap the connection with electrical tape.
If the vehicle has two constant power wire, use both of them. Connect one of the heavy gauge RED wires to
one of constant power wires and the other heavy gauge RED wire to the other vehicle constant power wire.
H2/5 PINK/WHITE PROGRAMMABLE OUTPUT, 2nd IGNITION/ACCESSORY CIRCUIT 30A
This wire may be used if vehicle requires more than one ignition. If the vehicle does not require more than
one ignition it can be reprogrammed to act as an accessory wire. This is helpful if there is 1 ignition and 2
accessory wires in the vehicle. See Feature Menu 2 and Programming System Features for instructions on
changing the function of this wire.

Auxiliary harness (H3)
H3/1 BLACK/WHITE (-) NEUTRAL SAFETY SWITCH INPUT
In most applications the neutral safety wire should be attached to a chassis ground. This does not apply to
vehicles that crank the starter while the transmission is in gear. If your vehicle cranks the engine while the
transmission is in gear you MUST call technical support at: 1-800-477-1382.
H3/2 VIOLET/WHITE TACHOMETER INPUT WIRE
Tachometer wire connections
Caution! In the following procedure DO NOT use a test light. Use of this
type of tester can cause grounding of sensitive electrical components, re-
sulting in damage, including damage to the power train control module.
A digital multi-meter is required to test for this wire.
Do not wear loose clothing that could get entangled in rotating engine
components. Ensure that your hands and arms are well clear of these
rotating components when working in the engine compartment. Lastly,
ensure that all wires and tools are clear of falling into or entanglement
with these rotating components.
Identify the suspected tach wire according to the web information. Next, place the black lead of a MULTI-
METER on the negative battery post and secure it. Put the multi-meter in the AC position and connect the probe
to the suspect wire with the red lead of the multi-meter. Then start the vehicle with the key. With the engine
at idle the multi-meter should read from .50 volts to 6 volts, and should fluctuate when you rev the engine.
Have a second person press the gas pedal to increase the RPMs and watch the meter display. When the RPMs
increase the voltage should rise slightly (not all tachometer outputs will rise when engine RPM increases).
Once the correct tachometer wire has been identified, turn the vehicle off.
Run the VIOLET/WHITE wire from the 5-pin harness through the firewall into the engine compartment along-
side the hood pin wire. Use the same procedure as with the hood pin wire and pull the wire through the grom-
met, taking extra care to keep it away from any moving parts or anything that will generate extreme heat.
Once the wire is run into the engine compartment, strip a small portion of insulation off the tachometer wire
in the vehicle and solder the green tachometer input wire to it. Then wrap the connection with electrical tape.
Important: If using a tach signal, the tach signal must be learned before
using the remote start. (See Tach learning section)

Safety Shutdown Wires
H3/3 BROWN (+) BRAKE SHUTDOWN INPUT WIRE
H3/4 GRAY (-) HOOD PIN SWITCH SHUTDOWN WIRE
With all ignition wires properly connected, find the appropriate safety shutdown wires. These are the brake
wire and hood pin wires.
Warning! These wires are meant to protect the vehicle and anyone near
the vehicle. They MUST be connected to prevent damage to the vehicle and
possible bodily injury.
First locate the factory brake wire using your multimeter. Find the switch at the top of the metal arm coming
off the brake pedal. Use your vehicle specific wiring information to determine the color of this wire. With
the black lead of your multimeter still in the kick panel, probe the suspected wire with the red lead of your
multimeter.
With the brake pedal at reset, the multimeter should read 0 volts. While watching the multimeter, depress the
brake pedal. The multimeter should read 12 volts. Once you have located the correct brake wire, solder the
small BROWN (H3/3) wire in the 5-pin harness to it and wrap the connection with electrical tape.
Warning! Do not use the vehicle until you confirm the operation of
the brake shutdown.
Installing the hood pin switch requires drilling a hole in a metal lip under the hood. Choose a location that
will allow the pin switch to be completely depressed when the hood is closed. The pin switch has a spade
connector on the bottom for the wire connection.
Always wear eye protection when drilling.
Crimp your spade connector to the hood pin wire, and run the wire into the vehicle's passenger compartment
through a factory rubber grommet , at the same time run the Tachometer Input wire [and Horn output wire
from the Optional Harness through the fire wall. To connect them use the following steps.
Using a sharp, pointed object, poke a hole into the grommet (being careful not to damage any existing wires
in the grommet) and attach the wire to the object with electrical tape. Pull the wire through the grommet,
taking extra care to keep the wire away from any moving parts or anything that will generate extreme heat.
An alternative to this method would be to find a spot on the firewall with sufficient clearance on both sides
and drill an access hole through the firewall. Take note of what is directly on the other side of where you are
drilling as to not puncture brake cylinders, computers, etc. Once the wire is run into the vehicle and secured
from any moving parts, solder the wire to the GRAY wire H3/4 of the 5-pin harness and wrap the connection
with electrical tape.
Warning! The GRAY wire must be connected. do not use the vehicle
until you confirm the operation of the hood pin shutdown. Improper
operation could result in serious injury or death.
H3/5 BLUE/WHITE (-) 200 mA 2ND STATUS/REAR DEFOGGER
This wire may be used to activate a bypass module in default mode, or it can activate the defogger circuit
when Feature Menu 2, option 8, is changed to an option setting.

Mounting the antenna
The best location for the receiver/antenna is centered high on either the front or rear windshield. For optimal
range, the antenna should be mounted vertically. It can be mounted horizontally in relation to the windshield
or under the dashboard away from metal, but range will be diminished. Window tint or dot matrix (small
black dots at top of windshield) can also affect range, so this should be a consideration when determining
the mounting location.
After determining the best mounting location, follow these steps:
1. Clean the mounting area with a quality glass cleaner or alcohol to remove any dirt or residue.
2. Plug the receiver/antenna cable into the receiver/antenna.
3. Mount the receiver/antenna using the supplied double-sided tape.
4. Route the receiver/antenna cable to the control module and plug it into the four-pin antenna connec
tor.
Important: To achieve the best possible range, DO NOT leave the an-
tenna cable bundled under the dash. Always extend the cable full length
during installation, regardless of the antenna mounting location.

Installation points
Important: The LED mentioned in the installation section references the LED (programming indicator) on the
Control Module, not on the remote control, unless otherwise stated.
Engine/voltage monitoring
During remote start, the system needs to know if the engine is running. The module does this by monitoring
the voltage of the vehicle's electrical system (or the tachometer: see next section).
Vehicle electrical systems usually rest at about 12.6 volts when the engine is not running. This system is pro-
grammed to detect the rise in battery voltage that occurs when the charging circuit activates after starting,
and keep the engine running if the rise is adequate. It will make up to three start attempts before discontinuing
due to an inadequate voltage rise.
Some vehicles have alternators that do not activate immediately or do not increase voltage sufficiently after
starting. This system will compensate by delaying the time before reading the battery voltage on the second
and third start attempts. This delay will allow most alternators to activate so the remote start continues to run.
The voltage read times are:
First attempt: 10 seconds
Second attempt: 20 seconds
Third attempt: 50 seconds
After the third start attempt, if the voltage increase is still not adequate to keep the engine running, the Tachom-
eter input option should be used to monitor the engine.
Virtual tach
Use of Virtual Tach does not require the Tach wire to be connected.
To program Virtual Tach:
1. After the install is complete, remote start the engine. The programming operation may require 3 cranks of
the starter before the engine starts and runs. Do not turn off the remote start if this happens, it is a normal
programming operation.
2. Once the engine begins running, let it run for at least 30 seconds.
3. Using the Remote, send the Remote start command to turn remote start off. Virtual Tach is programmed.
Virtual Tach is not recommended for diesel vehicles. Virtual Tach handles disengaging the starter motor dur-
ing remote starting – it does not address over-rev. For over-rev protection capability, the tach wire must be
connected.
Important: After successfully learning Virtual Tach, a small minority of vehicle start-
ers may over crank or under crank during remote start. Virtual Tach fine tune can be
adjusted, see Feature Menus and Programming System Features.
Tach learning
Note: Tach learning requires H3/2 (Violet/White) wire to be connected to Tach. If using Virtual Tach, this
procedure is not required and should not be used.
To learn the tach signal:
1. Start the vehicle with the key.
2. Within 5 seconds, press and hold the Control (Valet switch) button.
3. After 3 seconds the LED lights constant when the tach signal is learned.
4. Release the Control button.

18 © 2010 Directed Electronics. All rights reserved.
Reset and deletion
If a feature/Virtual Tach needs to be reset or the remote controls need to be deleted, use the following pro-
cedure.
1. Turn the ignition to the ON position (The heavy gauge pink wire must be connected).
2. Within 10 seconds, press and release the Control button (Valet switch): 2 times if you want to delete re-
motes, 3 times to reset features or 4 times to reset Virtual Tach. These features are described next.
Delete remotes: This feature erases all remote controls from the system memory. This is useful in cases
when a remote is lost or stolen. You can program new remote controls to the system, see Remote
Control Programming section of this guide.
Note: This does not reset the programmed features of the system or reset the Virtual Tach setting.
Reset Features: This resets all the system features to the factory default settings.
Note: This feature does not delete the remotes from the system or reset the Virtual Tach setting
Virtual Tach Reset: Deletes all previously learned values for Virtual Tach, and on the next remote start
sequence the unit begins virtual tach initialization.
3. Once you have selected the function step, press the Control button once more and hold it. The LED on
the control module flashes to confirm the selected functional step. Do not release the Control button.
4. While holding the Control button, press the single button on the remote control. The LED on the control
module flashes to confirm that the feature has been successfully reset. Once the feature is reset, the Control
button can be released.
Neutral safety switch interface
Some vehicles do not have an electrical neutral safety switch, but instead have a mechanical neutral safety
switch that interrupts the starter wire when the vehicle is in any drive gear. The remote start must be interfaced
before the neutral safety switch , to provide protection from starting in gear. However, some vehicles combine
the column shift and the neutral safety switch into one mechanical part, and in this case you will not be able
to interface the remote start before the neutral safety switch.
Important: You must complete the remote start system installation before doing the follow-
ing test. Ensure that the remote start system is functioning normally. This includes connect-
ing 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 releases 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 and the vehicle is a General Motors product or Dodge Dakota pickup, refer to
www. directechs.com for Document 1008 under the Resource tab, for an alternative shut-down method which
prevents the starter from engaging.
If the vehicle is not a General Motors product or a Dodge Dakota pickup, please call Directed Electronics
Technical Support at 1-800-477-1382 for an alternative shut-down method.

Remote start shutdown diagnostics
If the remote start activates but fails to stay running, the remote start module has the ability to inform you of
what may have caused the remote start failure. Before performing shutdown diagnostics it is important that
you let the remote start shut off on its own i.e. let it attempt to start 3 times then shut down, if this is not done
the unit will report the shutdown you used to shut off the remote start.
Note: Shutdown diagnostics does not report if the vehicles factory immobilizer is causing the problem.
To perform shutdown diagnostics:
1. With the ignition Off, press and hold the Control (valet switch) button.
2. Turn the ignition On and then back Off while holding the Control button.
3. Release the Control button.
4. Press and release the Control button. The LED on the control module flashes to report the last shutdown
for one minute or until the ignition is turned on, as shown in the following table:
LED Flashes Shutdown Mode
1 flash Runtime expired
2 flashes Over-rev shutdown
3 flashes Low or no RPM, low battery (voltage and virtual tach modes)
4 flashes Transmitter shutdown
5 flashes (-) Hood shutdown (H3/4 GRAY)
6 flashes Brake (+) Shutdown (H3/3 BROWN)
7 flashes Neutral safety shutdown (H3/1BLACK/WHITE)
8 flashes Wait-to-start timed out
Programming system features
The System Features Learn Routine dictates how the unit operates. It is possible to access and change most of
the feature settings using the Control module (Valet Switch) button.
1. Turn the ignition on, then off.
2. Select a Feature. Press and release the Control button the number of times corresponding to the
feature you wish to change. Then press and hold one more time to select the feature. The LED flashes
to indicate which feature # is selected.
3. Program the Feature. While holding the Control button, you can program the feature using the remote
control.
Pressing the button on the remote control selects the options in ascending order. The LED flashes indicatiing
which option is selected.
Once a feature is programmed:
• Other features can be programmed within the same menu
• The learn routine can be exited if programming is complete
To access another feature in the same menu:
• Press and release the Control button the number of times necessary to advance from the feature you just pro-
grammed to the next one you want to program next, then press the Control button once more and hold it.
The learn routine exits if any of the following occurs:
• The ignition is turned On
• There is no activity for 30 seconds
• The Control button is pressed too many times

1. Engine checking
1. VirtualTach: battery voltage drop/rise during cranking determines when the starter output is
released. During runtime, constant voltage level is monitored to determine if the engine is running.
2. Voltage: starter output during cranking is a programmed duration (Set in Cranking Time). During
runtime, constant voltage level is monitored to determine if the engine is running.
3. Off: starter output during cranking is a programmed duration (Set in Cranking Time). The remote
start keeps the ignition/accessories active for the programmed runtime whether the engine is running
or not.
4. Tachometer: tach input signal during cranking and runtime determines when the starter output is
released and if the engine is running.
2. Engine Runtime
• 12/24/60 minutes: sets engine runtime during normal remote start operations.
3. Park light output
1. Pulsed: the lights will pulse on/off during remote start.
2. Constant: the lights will turn on solid during remote start.
4. Cranking time
• 0.6/0.8/1.0/1.2/1.4/1.6/1.8/2.0/4.0 seconds: determines the starter output duration during
cranking for the ‘Voltage’ and the ‘Off’ Engine Checking Mode options.
5. Activation pulse count
• 1/ 2/ 3 pulses: sets the number of remote control commands received or Activation Input required
to activate and de-activate remote start.
6. 2nd Ignition behavior
1. Ignition 2: the relay will emulate the Ignition 1 output during remote start.
2. Accessory 2: the relay will emulate the Accessory 1 output during remote start.
