Cut injector wiring description
GAS INJECTOR CONNECTION/PETROL INJECTOR INTERRUPT:
- Sheath with ring A to connect to the gas injector at the interrupted petrol injector with the cut injector BLUE
AND BLUE-BLACK wires.
- Sheath with ring B to connect to the gas injector at the interrupted petrol injector with the cut injector RED
AND RED-BLACK wires.
- Sheath with ring C to connect to the gas injector at the interrupted petrol injector with the cut injector
GREEN AND GREEN-BLACK wires.
- Sheath with ring D to connect to the gas injector at the interrupted petrol injector with the cut injector YEL-
LOW AND YELLOW-BLACK wires.
- Sheath with ring E to connect to the gas injector at the interrupted petrol injector with the cut injector ROSE
AND ROSE-BLACK wires.
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.

English Changeover switch operation
The changeover switch supplied with the kit has one button, 7 LEDs and an internal buzzer.
This is used to select either the petrol or the gas fuel supply. Press the button one time to switch to
gas and press it again to return to petrol.
Rapid flashing – the control unit is prepared to start with petrol and switch automatically to GAS.
Steady on with yellow LED off – Gas operation.
Fuel level indicator; reserve RED LED, while the 4 GREEN LEDS indicate the fuel level (1/4, 2/4,
3/4, 4/4). The indicator is illuminated only when the gas mode is selected.
Steady on with Green LED off – PETROL operation.
Steady on with flashing Green LED – the control unit is prepared to start with petrol and
switch automatically to Gas.
SUCTION
MANIFOLDS
When the changeover switch indicates the fuel tank is in reserve and the gas pressure drops below a
set value, the control unit automatically switches over to gas. This prevents the engine from running
with an excessively lean carburetion, thus damaging the catalyser. Before returning to gas opera-
tion, fill up. The changeover switch signals the changeover to petrol due to low gas pressure by
activating the internal buzzer, illuminating the YELLOW petrol operation LED and by illuminating the
RED LED in an alternating pattern with the 4 GREEN LEDS. To make the changeover switch return to
normal operation press the BUTTON one time; the YELLOW LED will remain on to indicate that the
car is operating with petrol and the buzzer turns off.
If the car won't start with petrol (e.g. problems with the petrol pump, etc.), it can be started directly
with GAS. To do this follow the instructions listed below:
• insert the ignition key and press the button to switch the changeover switch to gas operation;
• remove the key;
• insert the ignition key and keep pressing the button (about 5 seconds) until the GREEN LED stops
flashing;
• now, start the engine without turning off the ignition key; the car will start directly with GAS;
• each time the car engine is turned off, the operation will have to be repeated to start in the EMER-
GENCY condition.
SUCTION
MANIFOLDS
The EMERGENCY function can be activated only if the changeover switch is illuminated
when the ignition key is turned
