Wiring suggestions:
High security:
Installing the two immobiliser blockers (supplied), to totally disable the ignition feed,
down stream of the ignition switch. This makes it very difficult to start the vehicle
without finding the blockers. Most ignition systems use one power feed in, and
several out.
Power feed in:
- Normally one or two power feeds in to the ignition switch.
Ignition switch position one:
- Auxiliary line: Radio and power sockets feed.
This line can be used for power to the Keypad, however not normally very
good for the blockers as it drops to ‘0’ voltage when in the start position.
Ignition switch position two:
- Power to the main electronic system, normally two
feeds from this position.
Breaking these two lines are normally sufficient to knock out dash, ignition
and all CAN devices including the ECU engine controller. Ensuring that
engine starting is impossible.
Ignition switch position three:
- Start.
If the correct feeds from position two have been blocked, the engine starter
may still operate, however the engine will not start, this is normal.
NOTE: Care must be taken not to induce any vehicle diagnostic error codes of
any kind whilst interrupting power supply to CAN bus devices on modern
vehicles.
Medium security:
Installing the two immobiliser blockers (supplied), to interrupt power to the starting
and fuel stop solenoids combined. On newer common rail engines with no fuel stop
solenoid, the ignition feed can be used instead.

any kind whilst interrupting power supply to CAN bus devices on modern
vehicles.
