Steering lock problem solved (for real)

SouthArk370Z

The ESCL does not have to be mounted to the steering column but it must be plugged in. A relay would solve the switches problem but there is other communication with one (or more) of the control modules (via CAN, IIRC, but wouldn't swear to it). Removing the fuse (or cutting the wire) only kills power to the motor that moves the pin - the electronics are still powered up.

Somebody did an autopsy on an ESCL with pics of the various components. I think I remember there also being some explanations of what the parts did.

I believe you are correct that it uses the CAN interface. In 370Z's with a steering lock assembly, obviously it must be in the unlocked position to start. But it has to tell the car the ESCL is in the unlock position. So this signal is needed in order to start the car, which is why you can't just remove the ESCL assembly completely. Thankfully, as you mention, the workarounds specified on this forum kill power to the motor that actuates the locking pin and still allow the unlocked signal to be sent to the car.
