I was in an early 2002 last week and it swung me. Instead of having just the standard none atc in it like below.
.
It had one like this below. At first I though he's just popped in a 2nd switch to make it look full but on investigation with the owners permissions it had a full switch mechanism in behind it and a blue wire to the control setup. And it illuminated.
Now the engine was gone as was a none runner but have I missed this in all these years or was this car a factory freak?
Edit.
Just like this. Was this a change between Mk1 and mk2 for none atc cars? Very curious.
