Before Starting the Installation
Please read all the installation guide before starting the installation. The installation of this item 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.
Installation Guide
Some things to remember about where to mount the control module:
Deciding on Control Module Locations
Never put the control module in the engine compartment!
When mounting the control module, try to find a secure location that will not require you to extend the
harnesses’ wires. Keep it away from the heater core (or any other heat sources) and any obvious leaks.
Some good control module locations are: Above the glove box, inside the center console, above the
under-dash fuse box, or above the radio.
The first step in hot-wiring a vehicle is removing the driver's side under-dash panel to access the starter
and ignition wires. If the control module is placed just behind the driver's side dash it can easily be
disconnected.
In order to have a maximize PKE induction range, the following antenna mounting options should be
discussed with the customer to better suit need.
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 car dealer.
To avoid accidental battery drainage, turn off the interior lights or remove the dome light fuse.

2.Mount the alarm antenna to the upper inside of the front windshield (see photo for example)
1.Assembly the alarm antenna (If equip with external antenna)
3.Fix the antenna with sticker and the plastic cap
4. Try your best to keep the antenna away from any metal product to avoid interference.

Some suggestions about the PKE antenna mount position for different vehicles:
IMPORTANT:
For sub compact, compact & sedan:
For optimal performance, mount the 4M PKE antenna in the headliner or below the rear deck.
Pickup (without cab):
Convertible:
Mount the 2M PKE antenna in front windshield pillar on driver side and the 4M PKE antenna behind the
rear seats.
Pickup (with cab) & cargo:
Mount the 4M PKE antenna in the bumper, behind the license plate.
Note: On vehicle with fiberglass bodies or convertibles, the PKE induction range will be increased.
Recommend the PKE antenna on position C. the PKE antennas should be mounted on the driver and
passenger side as the tailgate does not require to be controlled.
Mount the PKE antenna in the trunk will greatly affect and reduce the PKE induction range and overall
system working performance.
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 wire and the ignition wires will often be 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 connections and crimp connector
connection. When properly performed, either type of connection is reliable and trouble free.

As the PKE antenna is a directional antenna, the PKE induction range will be affected by the antenna
placement/mounting position.

IMPORTANT:
Never mount the PKE antennas on any metallic surface as this will decrease the PKE induction range
obviously
In order to have a stable PKE induction range, secure the PKE antenna & make sure they will not
move or dangle
The PKE antennas are fragile & easy to break, please handle with care when mounting them or
plug/unplug them when installation. Please also make sure they are mounted on a solid (non-flexible)
surface.
Recommended PKE antenna mount position
The recommended PKE antenna mount position is for reference only. And we’d like to recommend you
to adjust the PKE antenna mount position to get a maximum PKE induction range.

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.
Cheap electrical tape, especially when poorly applied, is not a reliable insulator. 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.

NOTE (1-7):
1.Connect all the +12V wire in your vehicle ignition wire harness with the +12V red wires in ec003;
2.White ignition 1 wire: When turn the key to ACC or ON position, this wire with electricity, when
starting the car, this wire still with electricity;
3.Brown ignition 2 wire: When turn the key to ACC or ON position, this wire with electricity, when
starting the car, this wire will cut off power suddenly at the moment of starting the vehicle;
Once the vehicle is started, both white & brown wires are with electricity.
4.If there is only one ignition wire in your ignition wire harness, connect it with the white ignition 1 wire
in ec003, no need to connect the brown ignition 2 wire
5.If there are 2 ACC wire in your ignition harness, connect both ACC wires with blue ACC wire in ec003
6.If there are 2 starter wires in your ignition harness, connect both starter wires with yellow starter wire
in ec003.
7. If your car is newer cars that’s no ACC (only ON & OFF), connect the ignition 1 wire in your vehicle
with ACC wire & ignition 1 wire from ec003.
We recommend that you do not use a factory ground. Ground all your components including the siren, to
the same point in the vehicle, (preferably the kick panel). Scrape away any paint and use a factory bolt or
make your own ground with a self-tapping screw and a star washer.
Please use a factory bolt or screw to attach all the black chassis ground wires securely as the photo
show as below:
Note 8
Wiring method of black chassis ground wire

GWR(-)( Ground while running) wire connection
If there is chip immobilizer in your factory OEM key fob, you should also need to add an extra bypass
module in order to make this device work properly. For most of the bypass module, which require a
GWR(-) (ground while running wire), and you can use an extra SPST relay to generate a GWR wire.
Method is as below:
Note 9:
connect with GWR(-) from bypass module
Connect with EC003
ACC or ignition 1
(ACC is recommend)
connect with chassis ground(GND)
You can also use a SPDT relay to generate
but no need to connect 87a on SPDT relay.

Note 11
Wiring method for fuel pump wire
The fuel pump wire is connecting with fuel pump or oil pump wire. If you can't find this wire in your car,
please connect it with constant 12V wire or tach wire in your car.
Wiring method for gray parking/hand brake wire.
If your car is manual transmission, connect the gray parking/hand brake wire with parking/hand brakewire
in the car
Note 12
If your car is automatic transmission, connect the gray parking/hand brake wire with chassis ground
If you connect with an electricity siren, such as 6 tone or 1 tone siren. Connect the pink wire with the
black wire from the siren and connect the other wire (usually a red wire) from siren to 12V wire.
Note 13
The pink wire for horn default is negative(-) output.
If your vehicle factory horn is negative, you can connect the pink wire with your factory car horn wire
directly.
If your car horn is positive output. Please add a SPST relay to change the polarity first, here is the
method:
When possible, place the siren on the same side of the vehicle as the control module, where its wires will
reach the control module’s wires without extending them. Always run the wires through the center of a
grommet, never through bare metal!
When installation the siren, please make sure which is downward for waterproof consideration
We do not recommend grounding the siren to its mounting screws. Instead, we recommend running both
the red and black wires into the passenger compartment and grounding to one common point for all
devices. Both wires are the same length and come already bonded together to make it easier. Whenever
possible, conceal your wires in the factory harnesses or in the same style loom as the factory.
Mount it where a thief cannot easily disconnect it, whether the hood is open or shut. Both the siren and
its wires should be difficult to find. This usually involves disguising the wire to look like a factory harness.

There are 8 different types of door lock systems (Type A - H). Please search the vehicle specific wiring
instructions online and the chart below to help determine which door lock system your vehicle uses. Most
vehicle factory door lock wires is smaller gauge and located in the driver’s kick panel or under the driver’s
dash.
Note: The most common type of door lock systems are Type A positive trigger, Type B negative trigger
and Type C reverse Polarity.
Type G: Positive (+) multiplex. One wire controls lock and unlock using resistor(s).
Type A: Positive trigger with three-wire (+) pulse controlling factory lock relays.
Type B: Negative trigger with three-wire (-) pulse controlling factory lock relays.
Type C: Reverse polarity, positive triggered
Type D: Adding one or more aftermarket actuators. These include central locking systems without an
actuator in the driver’s door, but with factory actuators in all the other doors. Type D also includes
vehicles without power locks, which will have actuators added.
Type E: Electrically-activated vacuum systems. The vehicle must have a vacuum actuator in each door.
Making sure that locking the doors from the driver’s or passenger side using the key activates all the
actuators in the vehicle. This requires a slight modification to the door lock wire harness.
Type F: One-wire system: cut to lock, ground to unlock.
Type H: Negative (-) multiplex. Same as Type G system, but uses (-) pulse instead.
The alarm default setting is type B negative (-) for locking and unlocking, if your car is with type B
negative central door locking, you can connect the white/black locking wire and white unlocking wire from
EC003 with your car locking and unlocking wire directly, or follow with the Type B negative trigger as

IMPORTANT TIPS:
1.Connect the black chassis ground wire first when making wire
connection to avoid damage on the device.
2.Once you finish all wire connection, test the function first and
remember to use the electrical tapes or strips to tighten all the wire
connection to avoid any poor connection between the control
module & wire harness.

TYPE B NEGATIVE TRIGGER
Type B: Negative trigger with three-wire (-) pulse controlling factory lock relays.
Two wires resting open circuit, one pulses ground for lock and the other pulse for unlock.
For this kind of trigger, the vehicle switch will have three wires on it, one wire will test ground all the
time. One wire will pulse (-) when the switch locks the doors, and the other wire will pulse (-) when
the switch unlocks the doors. This type of system is difficult to mistake for any other type.
There are 3 wires(+) pulse controlling factory locking relays, one pulses 12v for lock, one pulse 12V
for unlock, the last one is for constant 12V. Extra 2 SPDT relay are required.

Type D: Adding one or more aftermarket actuators
For this type of vehicle, there isn’t a motor in the driver’s door (central locking only operates from
the driver’s door). An extra door actuator is required.
Vehicles without factory power door locks require the installation of one actuator on each door. This
require 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.
These include central locking systems without an actuator in the driver’s door, but with factory
actuators in all the other doors. Type D also includes vehicles without power locks, which will have
actuators added.

Type E: Electrically-activated vacuum systems.
Polarity reverses on a single wire to lock and unlock. Please set the door lock time to 3.5 seconds
by a timer delay switch (not included).
The door locks are controlled by an electrically activated vacuum pump. The control wire will show
+12v when doors are unlock and (-) ground when locked.
The vehicle must have a vacuum actuator in each door. Making sure that locking the doors from
the driver’s or passenger side using the key activates all the actuators in the vehicle. This requires
a slight modification to the door lock wire harness.
NOTE: For this kind of central door locking, must program the lock pulse time to be 3.5 seconds.

Type F: One-wire system: cut to lock, ground to unlock.
Single wire that pulses negative to unlock, and open circuit to lock.
This type of door lock system usually requires a negative pulse to unlock, and cutting the wires to
lock the door. (for some vehicles, these are reversed). 2 extra SPDT relays are used to interface to
this type of system.

Type G: Positive (+) multiplex. One wire controls lock and unlock using resistor(s).
4.Once the resistor value(s) is determined, refer to the wring diagram for proper wiring.
Single-resistor style: 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.
1.Cut the output ire from the door lock switch/key cylinder in half;
Determining the proper resistor values: 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 multi-meter that is set to ohms.
Single wire positive central locking
IMPORTANT: to ensure an accurate resistance reading, do not touch the resistor or leads during
testing.
Two resistor type: 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.
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
multi-meter displays zero resistance in one direction, no resistor is need for that direction.
