INSTALLATION MANUAL 4693-4698

Electrical connections.
WARNING:
to prevent damage to the vehicle electrical system during installation, we recommend to
disconnect the battery negative cable and to reconnect it only after installation is completed. If the battery
is not disconnected, to avoid the possible generation of errors by the original central units of the vehicle, it
is necessary to pay attention during the connections and the use of the installation tools.
Pay attention when joining two or more wires. Avoid to make “quick connections” that do not ensure a good quality.
Also make sure that the wires of the Cobra 469X are routed so that they follow the original wiring of the vehicle to which
they should be joined with the raps.
The addition of fuse is required as speci
fi
ed in the main connection diagram.
In order to avoid human exposure to radio frequency electromagnetic
fi
elds, the distance of the device
respect to vehicle occupants must be greater than 0,25m
26 ways connector J pin-out
J-1 and J-2 Engine crank inhibition
:
to get the maximum security level to the system connect the two wires as shown in the
electrical diagrams to prevent the engine starter running. During the cranking phase, measure the value of the current in the circuit that
has been interrupt, to make sure that it does not exceed the technical speci
fi
cations of the product. Install an additional relay if required.
J-3 Output
:
make the connection depending on the chosen functionality (see “FUNCTIONS PROGRAMMING TABLES” manual).
J-4 Power blinker output
:
make the connection to the directon lights wires.
J-5 Power blinker output
:
make the connection to the directon lights wires.
J-6 Analogic input
: to be connected to a vehicle device (ex. passenger compartment fan heater) to reduce the US sensitivity
(step 7.12) or to be connected to a push-button for the driver recognition (step 7.22).
J-7 Negative input
: to connect to the wire of the bonnet original push button.
J-8 Cobra BUS
:
communication line for the connection of compatible Cobra sirens and sensors.
J-9 and J-10 Do not connect.
J-11
(see central door locking diagrams).
J-12
(see central door locking diagrams).
J-13
(see central door locking diagrams).
J-14 12 V connection (+30)
: the positive supply must be connected to a vehicle positive connection point upstream of the
fuse box. Fit a 15 A fuse as close as possible to the connection point.
J-15 GND connection
: the ground must be connected to a factory earth point or directly to the negative pole of the battery.
J-16 Negative output for modules
: active when the system is armed. To be used for the connection of compatible Cobra
modules.
J-17 Horn/loudspeaker negative output
: to program in line with the connected device. See electric diagrams and
functionalities programming tables. The output set automatically as per selected device, for horn choose also
fi
x or intermittent.
J-18 +15/54 connection
:
to be connected to a ignition key ON positive signal. The positive signal must be feeded while starting
the vehicle and when the engine is ON.
J-19 Negative perimetric input
:
to connect to the other doors wire, when the signal is separated from the one of the driver’s door.
