SA144U
All wires of the
SA144U
wiring are free and without connectors. This wiring is used on cars where other types
of wiring cannot be installed or where it is impossible to access the injectors’ original connectors.
To install this type of wiring, cut the negative wires of the petrol injectors in the order indicated in the figure.
The connection direction is very important. The
BLACK striped
wires should be installed toward the petrol
injection control unit and the others toward the injectors.
The
WHITE-RED
wire should be connected to any of the injector positives.
WARNING!
Follow the sequence of con-
nections. The
BLUE
and
BLUE-BLACK
wires must be
positioned at the gas injector
marked
A
. The others must
be connected as indicated in
the figure.

WARNING!
For a connection on a
3-cylinder car the
YELLOW
and
YELLOW-BLACK
wires
should remain disconnected.
See the diagram.

How to check what cut injector wiring to use
There are different types of cut injector wiring to match with the injection control unit.
NOTE: the cut injector wiring must be ordered separately since it is not included in the kit.
To know what type of cut injector wiring to use, you must first check, on the petrol injector connector,
on what PIN the injector positive is connected.
To identify which of the two wires is positive, do the following:
- detach all the connectors from the injectors;
- set a multimeter to measure DC voltage;
- put the negative probe to ground;
- put the positive probe into one of the two pins of the injector wiring;
- insert the key into the ignition and immediately check the multimeter reading.
If the multimeter reads +12 volts, that pin is the positive.
WARNING: the in12 volt on some cars might be timed; therefore the reading might
disappear a few seconds after the ignition is turned on. Check the polarity of all injector wir
-
ing connectors to make sure that they are all polarised in the same way.
EXAMPLES OF CONNECTORS MOST COMMONLY USED
SA144 - SA144INV for 4-8 cylinder cars (For 8 cyl. use 2 types of wiring).
Wiring types
SA144
and
SA144INV
are equipped with “BOSCH” type connectors to connect
directly to the petrol injectors. To know whether to use model
SA144
or
SA144INV
, check
the polarisation on the petrol injector wiring.
SA144
: use this if the positive of the petrol injectors is on PIN A and the negative is on PIN
B. Refer to figure 1.
SA144INV
: use this if the positive of the petrol injectors is on PIN B and the negative is on
PIN A. Refer to figure 1.
SA144J - SA144JINV- SA144SJ for 4-8 cylinder cars (For 8 cyl. use 2 types of wiring).
Wiring types
SA144J
and
SA144JINV
are equipped with “JAPAN” type connec-
tors to connect directly to the petrol injectors. To know whether to use mod-
el
SA144J
or
SA144JINV
, check the polarisation on the petrol injector wiring.
SA144J: use this if the positive of the petrol injectors is on PIN A and the negative is on PIN
B. Refer to figure 2.
SA144JINV
: use this if the positive of the petrol injectors is on PIN B and the negative is
on PIN A. Refer to figure 2.
Wiring type
SA144SJ
is equipped with JAPAN type pins and extended wiring for installation
on SUBARU cars with a BOXER engine. It is used
ONLY
if the positive of the petrol injectors
is on PIN B and the negative is on PIN A. Refer to figure 2.
SA144E
Wiring type
SA144E
is equipped with a single 6-pin connector. It can be used on some
types of Fiat, Citroen or Peugeot cars that use the same connector on the injector wiring.
To install and to know on what cars it can be used, follow the instructions included with
the wiring.
SA143 - SA143INV for 3 cylinder cars
Wiring types
SA143
and
SA143INV
are equipped with “BOSCH” type connectors to connect directly
on the petrol injectors. To know whether to use model
SA143
or
SA143INV
, check the polarisation
on the petrol injector wiring.
SA143
: use this if the positive of the petrol injectors is on PIN A and the negative is on PIN B. Refer
to figure 1.
SA143INV
: use this if the positive of the petrol injectors is on PIN B and the negative is on PIN A.
Refer to figure 1.
