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.
H1/5 EMPTY NOT USED
Horn wire
H1/6 BROWN (-) 200mA HORN OUTPUT
The Brown wire provides an output for activating the vehicle horn circuit or an external siren. The output is
programmable in Feature Menu 1/1 for the desired use.
Trunk release wire
H1/7 RED/WHITE (-) 200mA TRUNK RELEASE (CHANNEL 2) OUTPUT
The RED/WHITE wire can be used to activate a vehicle trunk release solenoid or to operate optional modules
that require a negative input. Whenever the button is pressed for a few seconds the system will disarm/unlock
and then activate this output. The output remains on until the transmitter button is released.

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 WHITE 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 igni-
tion, you can program the PINK/WHITE to be a 2nd accessory output. This setting may be found in Feature
Menu 2, 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 sstem. This wire will pre-
vent the host system from sensing that the ignition is on during remote start operation.

Additional heavy gauge harness wire description
H2/4 RED (+) 30A HIGH CURRENT 12V INPUT
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 connec-
tions 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 RED wires 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.

Door lock connections
1LIGHT BLUE (-) UNLOCK
2EMPTY NOT USED
3GREEN (-) LOCK
There are eight different types of door lock systems (Type A - H). Refer to the vehicle-specific wiring instruc-
tions on the web and the chart below to help determine which door lock system your vehicle uses. On
some late model GM vehicles a door lock data interface module may be required.
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
system has no factory relays. Relays (not included) will be required for this type of door lock system.
Type D: Adding one or more aftermarket actuators. These include slave systems without an actuator in the
driver's door, but with factory actuators in all the other doors.
Type E: Electrically-activated vacuum systems.
Type F: One-wire system - cut to lock, ground to unlock.
This is a very rare system found mainly in early 90's imports.
Type G: Positive (+) multiplex. One wire controls lock and unlock using resistor(s).
Type H: Negative (-) multiplex. Same as type G system, but uses (-) pulse instead.
All other door lock systems will require additional relays and/or resistors. A Directed Electronics 451M
Doorlock module can be used for these other applications. The 451M also includes diagrams and resistors
required for most applications.

17

Type A: Three-wire (+) pulse controlling factory lock relays
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.
Here is a test: Cut the wire that pulses (+)12V on lock, and then operate the switch. If the locks stop work-
ing, then you have the correct wire.
Many GM vehicles use Type A locks. However, some GM vehicles are Type C. This system usually appears
in older GM vehicles (1980-1995). The full-size pickups (1989-up), many of the Blazers, the Corvette,
1995 Cavalier/Sunfire 1993, and the newer Camaro/Firebird, all use Type C door locks, and cannot be
controlled without relays.
Almost all newer Fords are Type B. Ford builds no Type A systems. Chrysler now uses multiplex door lock
systems (Type G or H) that require relays and resistors to properly interface the circuit.
Important: Remember that these wires function in the reverse for Type
A and Type B.

Type B: Three-wire (-) pulse controlling factory lock relays
This system is common in many Toyotas, Nissans, Hondas, Saturns, and almost all newer Fords with keyless
entry systems. Use your vehicle specific wiring information to locate this wire. If you cut the wire and the locks
stop working, then you are on the correct wire.

Important: If your locks operate in the reverse, (lock when pressing
unlock, and unlock when pressing lock) then switch the lock/unlock wires.
Type C: Direct-wired reversing polarity switches
Interfacing with a reversing polarity system requires either two relays OR one DEI 451M (not included).
It is critical to identify the proper wires and locate the master switch to interface the door locks properly. This
door lock system will be referenced on our vehicle specific wiring information sheet as a "5wi" system.
Locate wires that show voltage on lock and unlock. Cut one of the suspected wires and check operation of the
locks from both switches. If one switch loses operation in both directions and the other switch operates in one
direction only, you have located one of the target wires. The switch that lost all operation is the master switch.
If one switch works in both directions and the other switch works in only one direction, you have a Type A
system. If both switches still operate, but one or more doors has 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 has been identified, cut both wires and interface as shown in the following diagram.

Caution! If these wires are not connected properly, (+) 12 volts will be
sent directly to (-) ground, possibly damaging the alarm or the factory
switch.
Type D: Adding one or more aftermarket actuators
In order for this system to control one or more aftermarket actuators, a DEI 451M (not included) or two relays
are required. Vehicles without factory power door locks require the installation of one actuator per door. This
requires mounting the door lock actuator inside the door.
Other 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. This type of installation is required to operate factory lock systems in Volvo (except
850), SAAB, and most Kia, Mazda, Isuzu and Subaru models. The fuse used on 12 volt inputs should be
7.5A per motor installed in the vehicle.
Important: Do not connect alarm outputs directly to the actuator.
Important: Directed offers actuators available at larger retail chain
stores.

Type E: Electrically-activated vacuum systems
Type E door locks are controlled by an electrically activated vacuum pump. Some Mercedes and Audis use a
Type D system. Test by locking doors from the passenger key cylinder. If all the doors lock, the vehicle's door
lock system can be controlled with just two relays (optional). 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.
Type F: One-wire system - cut to lock, ground to unlock
Type F door locks usually require a negative pulse to unlock and cutting the wire to lock the door. In some
vehicles, these functions are reversed. Type F door locks are found in late-model Hyundai, Nissan Sentras,
some Nissan 240SX, and Nissan 300ZX 1992-up. They are also found in some Mazda MPV's and some
Mitsubishi's.
One relay (not included) is used to interface to this type of system as follows:
