Hats off to you for trying it out and getting it to work. I agree regarding insurance, it's less likely to be a problem than leaving your car to warm up by running the engine without ERS! When I bought the part was actually still available in the UK, and I missed the chance to have it added by a month, after which they added GB to the list of excluded countries. There's been quite a few mornings of -10 when I'd have been very glad to have walked up to a pre-heated and toasty car...
