It was my understanding that the plugs shutdown immediately upon turning to position III. The violet wire gets the signal from the keyswitch and the relay shuts down. If the plugs remained on in position III and shut down in position II, how would the key switch be able to determine this, without some electronics?
The switch would need to remain on in position II on the initial glow, remain on in position III and then shutdown in position II when the key is released. This would be a benefit on start, for sure, but I don't see how the key switch could effect it.
