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 gure.
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 gure.

WIRES.
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 rst 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 injector +12 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 gure 1.
SA144INV: use this if the positive of the petrol injectors is on PIN B and the negative is on
PIN A. Refer to gure 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 gure 2.
SA144JINV: use this if the positive of the petrol injectors is on PIN B and the negative is
on PIN A. Refer to gure 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 gure 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 gure 1.
SA143INV: use this if the positive of the petrol injectors is on PIN B and the negative is on PIN A.
Refer to gure 1.
