Hi all. My three existing 12v (cigarette) sockets in my audi 2013 A5 tfsi are ignition controlled, that is, ignition on= socket on, ignition off= socket off. I know what fuse it is in the boot of my car, It is this fuse https://i.ytimg.com/vi/JJmOlmPnPsU/maxresdefault.jpg . I have confirmed this is the correct fuse by removing the fuse. I know it is constant live by using a multimeter and also to double confirm its constant live I connected a fusetap and 12v socket to it which stayed live all the time. The ignition control must obviously be after the fuse and into a relay !! but which relay ? and how do I connect into it for the 12v ignition controlled socket I want in the boot ?. Any help appreciated, Thank you.
