[url=https://www.house-improvements.com/forums/download/file.php?id=6663][/url] Under my sink is a switched receptacle. I need it split so that the top is constantly on. I saw your video on how to do this, but when I went to do it, there were only 3 wires going to the outlet. Is it still possible to do what I want easily?

Bought my home and the upstairs lights are controlled by 3 switches... two 3-way and 1 4-way. one 3-way is at the bottom of the stairs (3A) the other is at the top of the stairs (3B) and the 4-way is at the end of the hall-way (4A). sometimes when 4A is switched the light either does not go off or does not go on depending on the setup of the other switches. 3A has a one WRB wire with B hooked up to black screw 3B has 1 WRB wire and 2 WB with 2 W and 2 B marrated together, other B hooked up to black screw 4A has 2 WRB wire W are marreted, B & R hooked up to In and Out see pictures, they are in order 3A first, 3B next 2, 4A next 2. 3A...3B...4A...Status D.....D.....D.....ON D.....D.....U.....OFF D.....U.....D.....OFF D.....U.....U.....ON U.....D.....D.....OFF U.....D.....U.....OFF U.....U.....D.....ON U.....U.....U.....ON as you can see above there seems to be a problem when 3A is up the 4A stops working,seems to be a problem when both upstairs are up (3A doesn't work) and when 3B is up and 4A is down. Thanks in advance hopefully i can get some help here as I am very much out of my element [attach]110190[/attach] [attach]110191[/attach] [attach]110192[/attach] [attach]110193[/attach] [attach]110194[/attach]
