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.

This is the relay for the power outlets which is in the right hand(drivers side UK) cubby hole in the boot.
Mine as per picture was missing when I got mine as per picture.
You will need to probe the connectors with a voltage meter to determine what terminal does what.
