Steering Lock: cut one wire. /switch optional

Many thanks, folk, for the thank-you..s

And thanks to Gale Force too for his effort ....but

With great respect I found the shop manual a complete pain. It does not cater for such heathen manipulation of sealed steering locks and I doubt the manual writers had proper access to steering lock information anyhow.
(Nissan do not actually make the lock...made by security specialists, Huf Hulsbeck and Furst ... in the USA dontcha know... who probably hate to see this).

I got my head out of incredible repair manual confusion (partly shown in the Gale Force post) and inside the steering lock.

The electric motor in the lock is supplied by two Omron relays. The primary power source to each relay is singular (terminal #1 brown wire). As there's only one power supply it must be switchable on/off/pos/neg. That's logic.

That way the electric motor worm turns clock or anti-clock to drive a gear wheel with an internal cam which drives the lock element in or out, depending on that polarity at the motor.

Take away the power and the motor is stopped at "locked" or "unlocked".
....and for good....until power is re-applied (with any switch). The position sensors, including the one in the driver's door switch, will determine which rotation to use.

That's it: so broody difficult .. yet hindsight changes that: any questions?

Now: who'll tell me the numbers written under the "made in" ..... on a VVEL relay? (I can tell you where it is and how to look at it (5 mins).
