Hi guys, I have a similar issue, I’ve connected it as the diagram said in an earlier post but I have no way of determining which wire is the switch wire, I have tried all 3 black wires in the live port separately and either get power to the new light but can’t switch it off at the plug, get power to the new light and still can’t switch it off but also my other kitchen light stops working or I get no power to the light at all? I have very little knowledge on all of this and just wanted to install a new light haha any help would be greatly appreciated
