Wiring description
WIRING WITH BLACK CONNECTOR
1) SHEATH WITH 4-PIN CONNECTOR:
Diagnostic socket for PC connection through a serial interface.
2) SHEATH WITH WIRES:
BLUE: output + 12V output for gas operation (max. load supported 10A)
They control the pressure regulator solenoid valve and any gas ports (e.g. processor, etc.)..
BLACK: ground
DO NOT REVERSE THE POLARITY ON THE SOLENOID VALVES, IN PARTICULAR ON THOSE
EQUIPPED WITH AN INTERNAL DIODE.
3) SHEATH WITH WIRES:
BLUE-WHITE: output + 12V output for gas operation (max. load supported 10A)
It is used to pilot the posterior GAS solenoid valve on the converter and on the multivalve (for an
L.P.G. system) or on the solenoid valve of the CNG tank, if equipped.
BLACK: ground
DO NOT REVERSE THE POLARITY ON THE SOLENOID VALVES, IN PARTICULAR ON THOSE
EQUIPPED WITH AN INTERNAL DIODE.
4) SHEATH WITH WIRES:
ORANGE-BLACK: gas temperature sensor signal input
BLACK: gas temperature sensor ground
Connect to the temperature sensor positioned on the gas injector rail.
5) SHEATH WITH WIRES:
ORANGE: converter temperature sensor input
BLACK: converter temperature sensor ground
6) SHEATH FOR CONNECTION OF THE GAS INJECTORS A, B, C, D, E.
For the connection refer to the diagrams on pages 14 and 15.
7) SHEATH FOR CONNECTION OF THE GAS INJECTORS F, G, H, I, L.
For the connection refer to the diagrams on pages 14 and 15.

8) SHEATH WITH WIRES:
GREEN-BLACK: Do not connect.
BLACK: Do not connect.
9) SHEATH WITH WIRES:
RED-BLACK: connect to battery positive
BLACK: connect to battery ground
They are, respectively, the power supply and the ground for the control unit; connect them direct-
ly to the battery.
On the RED-BLACK wire connect the fuse supplied with the equipment, positioning it as close as
possible to the battery.
It is strongly recommended not to replace the fuse with another one with a higher am-
perage rating since it may cause irreparable damage.
10) Wiring with 4-pin connector:
Connect to the pressure gauge supplied with the kit (aeb 025).
The pressure gauge transmits the pressure difference between the gas injectors and the intake
manifolds to the gas control unit.
The bottom part of the pressure gauge has 2 nozzles identified as Pres. and V.;
- connect the pressure hose coming from the gas injector rail to the Pres. nozzle;
- connect the vacuum hose coming from the intake manifolds to the V. nozzle.
11) SHEATH WITH 4-PIN CONNECTOR:
For the connection to the changeover switch/indicator.
12) SHEATH WITH BROWN WIRE:
Needed to read the engine rpm. It can be connected to the engine speed indicator or directly to the
negative of a single coil or a bicoil.
The control unit software must be configured based on the connection made.
13) SHEATH WITH WIRES:
GREEN AND WHITE: For the connection to the level sensors (L.P.G. or NATURAL GAS PRESSURE)
they are used to read the quantity of fuel contained in the tank.
Change the wire connection and the control unit programming according to the type of sensor used
(see diagram on pages 13 and 14).
14) SHEATH WITH WIRES:
VIOLET: signal input only used to display the bank 1 sensor values on the PC (the control unit
does not need this connection to calculate the system operating parameters).
GREY: not used, therefore do not connect.
15) SHEATH WITH WIRES:
VIOLET-BLACK: signal input only used to display the bank 2 sensor values on the PC (the con-
trol unit does not need this connection to calculate the system operating parameters).
GREY-BLACK: not used, therefore do not connect.
16) SHEATH WITH YELLOW WIRE: Do not connect.
17) SHEATH WITH YELLOW-BLACK WIRE: Do not connect.
18) SHEATH WITH BLACK WIRE: Connect to battery ground.
