Precautions for Installation
●
When installing this product, do not use any electro-taps
Using the electro-tap makes the electrical co
ntact status unstable. This contact defect
may cause a malfunction in the
product and damage this product and the vehicle.
Be sure to use the attached splice
and dedicated tools such as cutting pliers
for electric
work to install this product securely and
properly.
●
Insulate the metallic portion of the
harness securely with electrical
tape.
●
Caulking the plug
●
Caulking the splice
(1) Peel off the coating of
the wires about 8 mm
(2) Cover with a sleeve
(3) Fold the wires
(4) Caulk securely
※
Check if caulking has been performed securely by referring to the following figure
Caulk the coating by these portions
Caulk the conductors by these portions
Make the caulking thrust into the wire
(2) Peel off the wires to be
branched about 10 mm
(3) Entwine the wires
(4) Caulk securely
※
Insulate the caulked portion securely with a vinyl tape
(1) Peel off the coating of the wires to
be connected about 5 mm

●
The ground conductor of this product has two branches (black and
brown).
This has a
very important significance to secure the voltage conversion accuracy.
Connect the ground conductor
by referring to the
following figure. Installing the
ground conductor in a different way from the connecting method specified by
APEXERA will give damage to this product and the mounted car engine.
The above figure explains only the connection of the ground conductor. For the
other signal lines, refer to page 6 and page 7. Be sure to wire the power cable,
ground conductor and other signal lines to the positions specified by APEXERA.
Correct Connecting Method for the Ground Conductor
Connect the ground conductor to two positions of the same line.
Be sure to connect the brown wire to the ECU side.
Allow a
space of
1 cm
or more
between the
connecting point of
the black
wire
and the connecting point of the brown wire.

Installation
●
Connecting the SAFC II
1.Remove the negative (
ー
) terminal of the battery
advice!
CAUTION
！
2.Locate the Electronic Control Unit (hereafter referred to as ECU) of the vehicle
by
referring to the vehicle specific
wiring diagram.
3.Connect the harness attached to the SUPER AFC II securely to the power cable of
the
vehicle harness, grounding wire, engine
rpm signal wire, thro
ttle signal wire, and
knocking signal wire from to the
ECU by referring to the vehicle
specific
wiring
diagram.
(Refer to page 8 and page 9.)
●
Before starting the wiring work, remove the negative terminal of the
battery.
Failure to do so way cause a
short circuit and damage the wires. If
the ECU connector
is removed while the battery is connected,
the engine warning lamp may light up
continuously regardless of whether the SUPER AFC II is installed or not.
At this time,
you must ask the dist
ributor of the car model to perform maintenance and ins
pection.
●
We shall not take any responsibility for damage to the vehicle or
related devices that may be
caused by installation error.
Connect the red wire to the power supply.
Connect the green wire to the engine rpm signal wire.
Connect the gray wire to the throttle signal wire.
Connect the black wire to the ground wire.
Connect brown wire to the ground wire.
Connect the purple wire to the knocking signal wire
・
・・
※
※
For models with a single knocking wire.
Connect the purple wire directly to the knocking
signal wire.
※
For models with multiple knocking wires (knocking signal
1,
knocking signal 2,
・・・
)
Refer to page 11 without making any connection at
this time.
There is some setting data on car audio, car navigation, etc. that is backed up by the battery power
supply. We recommend you to take a note of the data
in case it is lost.

Installation (cont.)
4.Cut the airflow signal wire or pressure signal wire of the
vehicle harness and install a
plug by referring to the vehicle spec
ific wiring diagram.
5.Connect the harness attached to the SAFC II to the plug ins
talled in step 4
6.Insulate the splice and unused plug
with electrical tape.
7.Reconnect the negative (
ー
) terminal of the battery.
●
Be sure to connect the black wire and the brown wire of the harness
attached to the SAFC II to the ground wire.
Failure to do so may cause this
product not to function properly, thereby causing
damage to the product and the engine.
●
When locating each wire, take special care not to cause a short
circuit.
An electrical fire may be caused or electrical devices may be damaged as a result.
●
Securely install the splice without any loose contacts.
Electric devices may be damaged as
a result.
