This extension loom is used when a steering lock with ignition switch is fitted under the steering column on cars fitted with a main wiring loom intended for the ignition switch fitted in the central console.

Triumph used this loom in markets where a steering lock was required during TR250, 5 and early TR6 production  when the 'rest of the world' markets did not require one.

In later TR6 production when the steering lock was standardised, the main wiring loom was extended to reach the ignition switch at the steering lock and this loom was deleted.

the loom is 600mm long with 2 white, 2 brown and white and one white and red wire, terminated with male Lucar connectors one end and female Lucars at the other.
