Interface Connector
The Easy Flash Module is a simple and effective way to flash the factory exterior lights of
supported vehicles. The system is easily installed in minutes and is a true plug and play solution for
most vehicles. If equipped, the module will flash the following lights: front low beams, front high
beams, front fog lights, front and rear turn indicator lamps, and side view mirror turn signal marker
lamps.
Unlike other solutions, the Easy Flash Module does not require any cutting or
reconfiguration of the vehicle’s wiring harness. This allows the module to easily be removed and
installed in another vehicle without repairing or replacing vehicle components.
The Easy Flash Module can be utilized by a wide range of markets. They include, but are not
limited to: police and firefighter vehicles (both volunteer and career), municipal vehicles, security
personal, road workers, towing vehicles, or utility vehicles.
Easy Flash Module Overview
Module Features
The Easy Flash Module features three main components: The OBD-II connector, the green
status LED, and the interface harness connector. These components are outlined below. More
information on the status LED can be found in the troubleshooting section.

Interface Harness
The purpose of the interface harness is to provide the on/off signal to the module as well as
provide a connection to the vehicles data network on select models. The on/off signal can be
provided via toggle switch or voltage input.
Currently there are four available interface harness options:
Dodge/Ram Truck with toggle switch
Dodge/Ram Truck with voltage input
Ford vehicle with toggle switch
Ford vehicle with voltage input
Some users may prefer the simplicity of the self-adhesive toggle switch harness while others may
wish to connect the on/off signal to a pre-existing switch (voltage input). The acceptable range for
the voltage input is 5-17 volts.
The Dodge/Ram interface harnesses differ from the Ford harnesses by the addition of two
vehicle network communication wires. Specific instructions on how to connect these wires can be
found in the installation section of this manual.
The interface harness plugs into the left side of the easy flash module 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!

4) Two wires will need to be tapped using the supplied red t-tap connectors. These wires are
the two leftmost wires in the connector.
The first wire in connector pin 1 is white
with an orange stripe. The second wire in
pin 9 is white with a gray stripe. The pin
numbers are molded into the back of the
connector for reference.
5) Place one of the two wires from the
previous step into the ‘V’ channel of the red
t-tap connector. (Figure 4)
6) Fold the t-tap connector in half by hand.
Using a pair of pliers, firmly squeeze the t-
tap connector. This will lock the connector
from opening as well as seat the wire in the
tap. Repeat steps 4 and 5 for the remaining
wire. (Figure 5 & 6)
7) Reconnect green 16 pin connector.

8) Connect the orange wire of the Easy Flash Module interface harness
to the white wire with orange stripe by inserting the spade
connector into the side of the t-tap connector. Repeat the process
by connecting the black wire of the Easy Flash Module to the white
wire with gray stripe. (Figure 7)
9) Route the Easy Flash Module interface harness down to the OBD-II
connector located on the underside of the driver’s side dash. Secure
with zip ties. Ensure the interface harness is routed in a manner that
does not interfere with normal vehicle operation.
10) Reinstall driver’s side dash end panel and driver’s door weather stripping by pressing back
into position.

Troubleshooting
Status LED
The green status LED indicates the current mode of the Easy Flash Module. Determining the
current module mode is the first step in troubleshooting any problem. There are a total of seven
modes. These modes are described in detail below.
Mode 1: Indicates the module is in the normal OFF state. In Mode 1, the status LED will blink
once followed by three seconds of non-illumination. The sequence will then repeat.
Mode 2: Indicates the module is in the first phase of the startup routine. In Mode 2, the
status LED will blink twice followed by three seconds of non-illumination. The sequence will
then repeat.
Mode 3: Indicates the module is in the second phase of the startup routine. In Mode 3, the
status LED will blink three times followed by three seconds of non-illumination. The
sequence will then repeat.
Mode 4: Indicates the current vehicle is not supported by the device. In Mode 4, the status
LED will blink four times followed by three seconds of non-illumination. The sequence will
then repeat.

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.
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 For most vehicles, there are no required tools. For Dodge / Ram Vehicles the use of
a standard pair of pliers is required.
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.
What does the blinking green status light mean?
o The green status light communicates the current mode of the module. This mode is
used for troubleshooting and is explained in more detail in the Troubleshooting
section.

Page 11
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
be supported due to the technical aspects of how the vehicle operates. This is
currently true for all GM vehicles. If there is a specific vehicle that you would like to
request, we would love to hear from you at support@SpeedTurtleEngineering.com.
Occasionally, I hear the turn signal indicator click or see the dash back lights flicker. Is this
normal?
o Yes, this is normal and is not detrimental in any way. Turning the vehicle’s headlight
switch to the park or ON position while the module is active will mitigate the
occasional flicker of the dash back lights.
I already have a device plugged into the OBD-II connector. Can I still use the Easy Flash
Module?
o Dodge / Ram vehicles are not compatible with concurrent OBD-II devices. Other
vehicles may be compatible with concurrent OBD-II devices by using a Y-cable.
