Having just baught a new van it's something I shall have to consider as well.
Seems a lot of Google searching is on the cards to find answers.
I fear dealers have as much clue as owners do at the moment.
I will certainly follow this tread with interest and post any information I find.

Does pin 10 offer power to the atc devise on newer vans?

Caravan ATC is connected to pin 9 which is a permanent live, On my new XC90 there is quite a long delay from when plugging in to the socket to ATC activating, I thought my pin 9 was not connected or fused up at first as ATC activated when ignition was turned on instantly, I had my dealer check and pin 9 was live, Others on here have reported this delay so it looks to be normal for new SPA models. On my old XC90 the ATC activated instantly when plugged in.
