The module has two switch inputs as well as an existing vehicle button (most vehicles) that
can be configured to activate the module either through a long press or quick cycle.

The EFM 2.0 has applications in a wide range of markets. They include, but are not limited
to: police and fire, municipal vehicles, security personal, road workers, towing vehicles, or service
vehicles.

Easy Flash Module 2.0 Overview

Module Layout

The Easy Flash Module 2.0 features six main components: The OBD-II connector, switch
interface connector, power and mode LEDs, pattern button and micro USB port. These components
locations are outlined below.

Switch Interface Harness

The purpose of the switch interface harness is to provide an ON/OFF signal to the module.
There are two switch interface harness options:

Toggle Switch Harness: This harness provides a simple ON/OFF toggle switch with adhesive
backing. There are two internal LEDs to the toggle switch with green indicating the switch is
OFF and orange indicating the switch is ON. While this is the simplest of the two harnesses

Easy Flash Module 2.0 User Manual

to install, it only provides one of the two possible switch inputs. The toggle switch harness is
connected to Input 1 on the module.

Voltage Input Harness: This harness provides two ‘flying lead’ input wires. Each wire will
accept a 5 – 17 volt input signal from a switch or light controller of your choice. The white
wire corresponds to switch input 1 and the green wire corresponds to switch input 2.

Both switch interface harnesses plug into the right side of the EFM 2.0 using a small black
square connector. It is secured by a locking tab attached to the top of the harness connector. To
disconnect the interface harness, depress the connector’s locking tab and gently pull the connector,
NOT the wires!

Installation

1) Chrysler / Jeep / Ram vehicles model year 2018 and above will need to install an OBD pass

through connector for operation. Instructions for installing the OBD pass through connector

are outlined in the OBD pass through connector manual available on the Speed Turtle

Engineering support webpage. All other vehicles can skip this step.

2)
a. If using the toggle switch interface harness, mount the toggle switch using the self-

adhesive pad located on the bottom of the switch in a safe and easily accessible
location. Route the switch harness in a manner that does not interfere with normal
vehicle operation. Secure with zip ties.

b. If using the voltage input interface harness, connect the white and green wires to a

5-17 volt fused switch source. Route the voltage input wire in a manner that does
not interfere with normal vehicle operation. Secure with zip ties. Remember that
the white wire will control Input 1 and the green wire will control Input 2.

3) Plug the small black square connector on the interface harness into the right side of EFM

2.0.

4) Turn the vehicle ignition to the ‘Run’ position.

5) Plug the EFM 2.0 into the OBD-II connector of the vehicle. The OBD-II connector is located

under the driver’s side dashboard. Location will vary by vehicle; however, the connector will

be identical for all vehicles.

6) The module will run through a sequence of checks and configurations. Within a minute the

module should enter Normal mode. This will be indicated by a flashing green power LED
(lightning bolt) on the module. If the module does not enter normal mode after one minute,
remove the module, wait at least 30 seconds and reconnect the module to the vehicle. If
normal mode is not reached consult the Troubleshooting section of this manual.

7) Test the module by activating the switch or voltage input. If the module does not work as

expected see the Troubleshooting section of this manual.

8) The module is now installed and may remain in the vehicle indefinitely. To uninstall simply

remove the switch input harness and disconnect the module from the OBD-II port. No
additional steps are required.

Module Operation:

Switch Inputs

EFM 2.0 has two switch inputs available for module activation, switch 1 and switch 2
respectively. By default, switch 1 and switch 2 inputs are enabled. Switch inputs can be disabled if
desired using the STE Configuration Utility available on the Speed Turtle Engineering website.

Toggle Switch Harness: The toggle switch harness controls switch 1 only. Internal to the toggle
switch harness are two LEDs. The green LED will illuminate when the switch is in the OFF position. A
yellow LED will illuminate when the switch is in the ON position.

Voltage Input Harness: For the voltage input harness the white wire controls switch 1 and the green
wire controls switch 2. Voltage input wires can be connected to a switch or controller of your choice
with a voltage of 5-17 volts. Voltages higher than this can permanently damage the module.

Integrated Vehicle Switch

In addition to the switched inputs, EFM 2.0 can also be activated by an existing vehicle
button either through a fast double press or a long press. Table 1 identifies the vehicle button can
be used for activation in specific vehicle models. The integrated vehicle button input is disabled by
default. It can be enabled using the STE Configuration Utility.

Active Modes

EFM 2.0 has four active modes that can individually be configured for both flash pattern and active
lights. Active modes are shown below in order of priority:

• Park Mode – Park mode is active when switch input 1, switch input 2, or the integrated

vehicle switch is active and the vehicle transmission is in park. Park mode pattern and active
light configurations take precedence over any switch configurations. Park mode is disabled
by default.

• Switch Input 1 Mode – Switch input 1 mode is active when the toggle switch harness is in

the ON position or when the input to switch input 1 is between 5 – 17 volts. Switch input 1
mode pattern and active light configurations take precedence over switch input 2 and
integrated vehicle switch configurations. Switch input 1 mode is enabled by default.

• Switch Input 2 Mode – Switch input 2 mode is active when the input to switch input 2 is

between 5 – 17 volts. Switch input 2 mode pattern and active light configurations take
precedence over integrated vehicle switch configurations. Switch input 2 mode is enabled
by default.

• Integrated Vehicle Switch Mode – Integrated vehicle switch mode is active when the vehicle

button is activated according to Table 1. Integrated Vehicle Switch Mode is disabled by
default.

For example, if park mode is disabled and switch input 2 is active, EFM 2.0 will use the
configurations saved for switch input 2. If switch input 1 is then activated, EFM 2.0 will use the
configurations for switch input 1 due to its higher priority. Alternatively, if park mode is enabled, the
vehicle is in park and switch input 1 is activated, EMF 2.0 will use the park mode configurations due
to its higher priority. Once the vehicle transmission is taken out of park, EFM 2.0 will use the
configurations for switch input 1.

Pattern Selection

There are ten selectable patterns for every vehicle. These patterns are adjusted per vehicle to
ensure the best possible pattern selection based on supported vehicle lights and light locations.

Easy Flash Module 2.0 User Manual

V1.3 Speed Turtle Engineering LLC Page | 12

There are two ways to configure the pattern for switch input 1, switch input 2 and the integrated
vehicle switch.

Using the Pattern Button: On the front of the EFM 2.0 there is a gray circle with a ‘PATT’ marking.
There is a small push button switch located in this location beneath the front faceplate that can be
activated by pressing firmly in the gray circle. You should hear a small click when activated. To set
the pattern for a specific switch input use the following steps: NOTE: If Park mode is enabled, use
the STE Configuration Utility to modify configurations.

1. Activate the switch input of the switch you wish to change the pattern of.

2. Firmly press the ‘PATT’ button on the EFM faceplate and hold for 3 seconds.

3. The green PWR (lightning bolt) and blue MODE (cube) LEDs will blink in unison. The number

of blinks correspond to the current pattern (1 – 10).

4. Press the ‘PATT’ button to advance to the next pattern.

5. Once you have selected a pattern press and hold the ‘PATT’ button for 3 seconds. This will

save the pattern configuration for that specific switch.

6. Turn the switch input off.

Using the STE Configuration Utility: Individual switch patterns can also be configured using the STE
Configuration Utility. Using this PC based tool, patterns for switch input 1, switch input 2, integrated

switch input and park mode can be configured.

Individual Lamp Configuration

Much like the pattern configuration, the EFM 2.0 allows individual lamp configuration of
each active lamp mode. These individual lamp configurations can be configured using the STE
Configuration Utility. This configuration allows specific lamps to be deactivated

Module Overrides

EFM 2.0 has four built in light overrides to ensure normal vehicle light operation is
unaffected for specific lamps. Overrides include headlamp, turn signal, reverse and brake lamp. All
module overrides are enabled by default. However, headlamp and turn signal overrides can be
disabled using the STE Configuration Utility. Reverse and brake lamp overrides cannot be disabled.

Frequently Asked Questions

• How does it work?

o Traditionally, flasher systems operated by physically cutting the power wires to

specific lights and splicing control electronics in-line. The Easy Flash Module takes a
different approach by simply commanding the vehicle to illuminate specific lights.

Easy Flash Module 2.0 User Manual

V1.3 Speed Turtle Engineering LLC Page | 15

This approach is faster and easier to install, less intrusive to vehicle wiring, and more
cost effective.

• Does the Easy Flash Module support my vehicle?
o The Easy Flash Module currently supports a wide range of vehicles. A list of

supported vehicles and model years, at the time of printing, can be found in the
Currently Supported Vehicles section of this manual. The most up to date list can be
found at SpeedTurtleEngineering.com .

• Are there any tools required for installation?
o There are no required tools

• Can the module be connected to my own switch or activation signal?
o Yes, the module can be connected to an existing switch or voltage source for

activation. Users that wish to provide their own input signal should order the Easy
Flash Module with the voltage input harness. The module will accept activation
signals in the range of 5 – 17 volts. Voltages higher than 17 volts can permanently
damage the module.

Will the module work in more than one vehicle?

o Yes, the Easy Flash module will work in any supported vehicle. There are no

restrictions on how many vehicles you can use the module on. If the module is
planned to be used on more than one vehicle, purchasing a separate vehicle
interface harness for each vehicle may be convenient.

• My vehicle is not on the supported list. Are there any plans to support it?
o At Speed Turtle we are continuously working to provide you with more supported

vehicles and model years. With that said, there are some vehicle lines that cannot
