Cobra 4627 CAN/PLIP Installation Manual page 6

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 4625 - 4627 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 specifi ed in the main connection diagram.
J-1 Analogic input: make the connection if required by the specifi c vehicle CAN installation sheet.
J-2 Analogic input: make the connection if required by the specifi c vehicle CAN installation sheet.
J-3 Logic blinker output: make the connection if required by the specifi c vehicle CAN installation sheet.
J-4 Analogic input: make the connection if required by the specifi c vehicle CAN installation sheet.
J-5 Analogic input: make the connection if required by the specifi c vehicle CAN installation sheet.
J-6 Analogic input: make the connection if required by the specifi c vehicle CAN installation sheet.
J-7 +15/54 connection: if the signal is not detected from the CAN network, connect this input to the ignition key on, checking
that the wire is permanently fed during the crancking phase and while the engine is running. Fit a 3A fuse as close as possible to
the vehicle connection point.
J-8 GND connection: the ground must be connected to a factory earth point or directly to the negative pole of the battery.
J-9 12V connection (+30): the positive supply must be connected to a vehicle positive connection point upstream of the fuse
box. Fit a 15A fuse as close as possible to the connection point.
J-10 Cobra bus: communication line for the connection of compatible Cobra sirens and sensors.
J-11 and J-12 CAN H/L: to connect as shown in the specifi c vehicle CAN installation sheet.
J-13 Negative input for additional modules: to be used as a triggering input for the connection of compatible Cobra modules.
J-14 Negative output for modules: active when the system is armed. To be used for the connection of compatible Cobra
modules.
J-15 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-16 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 7.18*). If the wire connection of this input is required
in the CAN application, it can not be used for the functions as in step 7.12* and 7.18*.
J-17 Negative input to enter in programming procedure/to connect bonnet pushbutton: if connected to
ground the system will enter in the programming procedure for all applications not able to detect the original bonnet pushbutton. If the
siren is a wireless one this input must not be used for the bonnet pushbutton connections. For wired siren or loudspeaker this input
must be used for the connection of the bonnet pushbutton as indicated in the specifi c vehicle CAN installation sheet.
J-18 Analogic input: make the connection if required by the specifi c vehicle CAN installation sheet.
J-19 Logic blinker feedback input or power blinker output: make the connection if required by the specifi c vehicle
CAN installation sheet.
J-20 Power blinker output: make the connection if required by the specifi c vehicle CAN installation sheet.
