10.0 - ELECTRICAL CONNECTIONS WITH SPECIFIC
WIRING HARNESS
After selecting the appropriate position for the alarm system and accessories
(electronic key receptacle, seat/topcase contact switch), proceed with the
electrical connections.
P ay special attention to the following instructions in order to ensure proper
electrical connections and refer to the relative drawings

10.1 - ENGINE IMMOBILIZATION CONNECTIONS

!
Disconnect the ignition switch connector (or the factory installed device for
engine immobilization) from the vehicle main wiring harness connector (fig.2)
!
Insert the alarm harness connectors as follows: one into the ignition switch
connector (or the factory installed immobilization device) and the other into
the vehicle main wiring harness (fig.3).
!
Connectors cannot be inverted because they are polarized

10.2 - TURN INDICATOR CONNECTIONS

!
C onnect the alarm harness wires to the the same color vehicle wires that
provide a positive feed to the turn indicator lamps.
10.3 - GROUND CONNECTION (WHEN NOT AVAILABLE ON THE
IGNITION SWITCH
!
If the vehicle ignition switch does not have a ground wire (ex. four-stroke
engine vehicles) the alarm ground wire must be connected to a vehicle
ground point (ex. turn indicator negative lead).
!
D o not connect the alarm ground cable to the vehicle fram

10.4 - ELECTRONIC KEY RECEPTACLE WITH BUILT-IN LED

C onnect the receptacle 2-way BLACK connectors to the relative alarm unit 2-way
BLACK connectors.
Wires inside the receptacle connectors are RED and BLACK and they are
BROWN and GREEN in the alarm unit connectors.

11.0 - DIODE INSTALLATION

!
Activate one of the turn indicators, turn ignition OFF and arm the alarm.
!
If the instrument panel comes on when the turn indicators are activated, a
diode needs to be installed (see diagram below).
!
If the instrument panel does not light up, do not insert a diode.
CAUTION
Adiode is not really necessary if, when the alarm is armed, the instrument
panel comes on.
No damage will be incurred to the vehicle in case a diode is not fitted.
