pixel_player444432947 Do you mean after you have placed the Electrical Boxes on their spots? It would be nice to see how you placed them since each has to go on a specific spot. Just placing them all on spots won't work and doesn't mean there is a bug if they aren't properly placed. The green ones need to connect to the green wires and the red ones to the red wires. But you need to put the box on the spot that has its wires coming out the proper way, so that it connects to the wires. If you don't, then there isn't a proper connection and the door won't open.
