1967 68 69 70 EU DLX LED Tail-Light Kit Installation:
First we will remove the old
original flasher module. The
original flasher may be located on the driver side of the
car near the fire wall as
shown on the following picture or near the radio on either the passenger side or
driver side.
The installation procedure is
as follows:
1)
Remove the existing
flasher module
2)
Connect the new flasher
wires red and green to
the Mustang’s wiring.
3)
Connect the black
“ground” wire from the
new LED flasher module
to a good chassis grounding point.
Simply unsnap the cylinder
shaped flasher module and
remove. 67/68/69/70 Mustangs have TWO flasher
modules. One for 4 way
flashers and one for turn
signals. Be sure and replace the correct one (turn
signal)! Listen for the clicking sound when your turn
signal is activated to aid
identification.
plugging in the red wire to the Mustang’s yellow-orange
wire and the green wire to the Mustang’s blue wire.
You now have only to attach the black wire to a convenient chassis ground point A likely place to connect the
black ground wire will be under a mounting screw on the
dash or on any metal part screwed under the dash.
Just make sure that there is a good electrical connection
between the black wire and the cars chassis.
Simply unsnap the cylinder
shaped module and remove
the push on connectors.
These will be attached with a
green wire and a orange/
yellow wire.
The LED flasher module has
three color coded wire leads.
Red, Green, and Black.
Once you remove the old
module install the new LED
flasher module by simply
GREEN
RED
Be sure and wrap each connector in
electrical tape before final installation
of the flasher module.

screw which holds the
LED board assembly
onto the 1157 lamp
base. The base will
now be free from the
board for insertion into
the socket.

MODULE INSTALLATION
Now install the LED taillight
modules. Each module is
clearly marked “R” for right
and “L” for left.
Be careful to install only the
Left module in the Left taillight and the Right module in
the right taillight. Otherwise
the sequence direction will
not be correct though no
harm would come to the
modules themselves.
You will follow the procedure below for installing
each LED taillight module.
A.
Remove lens, frame,
and incandescent bulb.
B.
Verify that the ignition is
off and that the cars
lights are OFF too
1)
Unscrew the small #4
5
Insert the base into the
existing Mustang lamp
socket. Carefully align
the socket pins with the
slot. NOTE that the
pins are offset and
can only go in one
way!
3)
Gently push the LED
taillight module into
the socket making sure
that the alignment pins
and the socket slots are
properly aligned.
4)
Now push in on the
base and rotate to the
right to lock in the
base.
5)
Pick one of the attached spacers depending on the socket
you have in your car. If
your car has the original Ford sockets which
protrude from the
housing about 1 inch
use the shorter spacer.
If the original lamp
sockets have been replaced use the longer
spacer.
6)
Slip the spacer over
the supplied 1 inch
screw. Which has
been passed through
the board just as originally supplied.
7)
Re-secure the board
onto the base by
screwing the screw
into the tapped portion
of the base standoff.
Be sure and align the
LED module to be
straight. Also be sure
and check for shorts
between the board and
the lamp housing.

NOTE:
For 67,68, 69 and
70 EU models each
lens is provided in
two pieces. Place
the lenses behind
the thick gasket
and apply a bead
of RTV between
the amber lens
and the red lens.
There will be a
small gap between
the red lens and
the amber lens.
This is normal and
can be filled with
RTV to ensure a
water tight seal.

Connecting Braking Sensor Wire
ORANGE/BLUE
RED—Driving Lights
Step 1: You must attach a
wire tap connector to the
ORANGE/ BLUE wire connected to the lamp socket
boot connector on one side
of the car as shown above.
You must also attach a wire
tap connector to the
GREEN/ORANGE wire connected to the lamp socket
boot connector on the other
side of the car.

Step 2: Connect the Brake
Sensor wire from each
module by drilling a hole in
each housing and routing
the sensor wire so that it
can plug into the corresponding sire tap connector on the opposite side of
the car.
Alternately to avoid drilling a hole in the lamp
housing the Brake sensor
wire from each LED module can be routed through
the housing opening in
the taillight panel. Be
sure and add insulating
tape around the edges of
the housing opening to
prevent the Brake sensor
wire from being cut.

Trouble Shooting Guide:
Our NEW improved design works
as follows:
• With brake applied and no
turn signal active. Two inner
sections light full bright red.
•
•
•
•
“Remember...
you are
dealing with
electrical
components
that are over
40 years old!”
With driving lights ON and
no turn signal active. Two
inner sections light to half
bright red.
With driving lights OFF and
turn signal ON. Outer amber
section blinks on/off for turn
signal indicaiton.
With driving lights ON and
turn signal ON. Outer amber
section blinks ON/OFF. Two
inner sections stay lit to half

With brake applied and turn
signal ON. Two inner sections are steady bright red
the outer amber section
blinks.
Note: A slight blip of the red
lights will be seen when the
driving lights are on and the
turn signal is active. This is
normal operation.
If you have any problems with
your installation please feel
free to give us a call.

Most Taillight problems are
due to faulty wiring or bad
socket connections.
Remember unless you have
replaced the wiring or taillight
sockets in your Mustang you
are dealing with electrical
components that are over 40
years old!
Corrosion and rust can take
their toll. If you have any troubles first re-install the standard
incandescent lamps and ensure that the signals, brake,
and light functions work prop-
erly. If you see any problem with the brake or signal light functionality using
the incandescent lights
your system will not work
with the new Mustang Project LED taillight modules.
Carefully check for bad or
rusted sockets. If you see
evidence of corrosion carefully clean the contacts and
re-test.
Old wiring can also be a
source of problems. Look
for broken or frayed insulation if you see intermittent
functionality.
Below is a list of trouble
shooting keys:
Problem: Lights flicker.
Flickering lights are often
caused by failing alternators or bad regulators. The
alternator may still function
well enough to marginally
charge the battery but diode failure in the alternator
can cause flickering taillights.
It is also possible that the
regulator is failing. The
original Mustang electromechanical regulators are
famous for unusually failures. Always replace your
regulator with a Motorcraft
direct replacement regulator available at most auto
parts stores.
If you suspect a regulator
or alternator problem you
need to replace these items
before you car is stranded!
Doing so will also prevent
flickering of the LED taillights.
Problem: Taillights don’t
sequence but do light if
headlights are on.
Most likely this is due to a
bad socket. It can also be
caused by incorrect instal-
lation of the Mustang Project flasher module or improper connection of the
flasher module ground.
Carefully clean the socket
and use a mild sandpaper
on the Taillight Module
contacts to clean off any
debris left by a dirty
socket.
Problem: Taillights sequence but taillights do
not illuminate when headlamps are on.
Most likely this is due to a
bad socket. Carefully
clean the socket and use a
mild sandpaper on the Taillight Module contacts to
clean off any debris left by
a dirty socket.
Problem: Taillights function abnormally in the
rain.
This is probably caused by
water in the Taillight
bucket. Check for evidence of water and repair
any gasket leaks. The Mustang Project Taillight modules are coated to protect
against water damage but
they will not operate if too
much water is allowed to
cling to the circuit boards.
Problem: Taillights don’t
fit properly into sockets.
Review the socket section
at the beginning of this instruction sheet for adjustment with misaligned sockets.
Be careful to always ensure that you have removed the boot connector
in the back of the light
housing BEFORE inserting the taillight modules.
Failure to do so can cause
any or all of the above
symptoms!
