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.
