Brake/stop light wiring variations

["Walter" <Whalt@xxxx>]

I have noticed two wiring variations on DeLorean stop lights and am
wondering if anyone can say what this is about.

On my car VIN 3633, the stop light circuit is always hot meaning that even
though the ignition is switched off, the stop lights still come on when I
press the brake pedal.

On Randy's car VIN 3228, the stop light circuit is only hot when the
ignition is switched on. If you are sitting in the car with the key removed
from the ignition and press the brake pedal then the stop lights won't
operate.

Can anyone say which variation is the norm on DeLoreans? Is it likely that
both cars left the factory in this configuration or was one of the cars
modified?
