2018 4/4. Found that the accessories socket remains permanently live. I have a ctek adapter. Plugged that in and connected the ctek and it works fine. Found that the plug needs a bit of wiggling to seat it and make contact, but otherwise okay. Will probably get around to a direct to battery connector as that is what I have done on all my previous vehicles.
That is how I used to work but I noticed that the connection could become unreliable in the winter - even if undisturbed. I installed a fused fix connector and all is now reliable.
