6. Crank Inhibit (Immobilisation) Black/Blue wires (2 wires)
The starter circuit is the ONLY circuit that Thatcham permit an installer to cut. The
cut must only prevent the vehicle from starting and must not prevent it from
running.
Under no circumstances must any other cut be made including ignition, fuel or any
other engine run cut.
The installer will need to find either the wire leading directly to the starter solenoid
or a wire that controls a starter relay.
The crank inhibit relay will take a maximum load of 25 amps. Connect one
black/blue wire to both ends of the cut wire.
There are two versions of the loom for this system available for either 12 or 24 volt
applications, please specify, when ordering, which of the two looms are required.
Part numbers are:
12 volt loom (18amp) HAST50CAT5
24 volt loom (30amp) HAC524V
