El Wire Help

Hey guys, So I am trying to have 3 different arduinos connected to el wires. Each ardruino is controlled with bluetooth and I have already made app for it. My problem is I do not undrestand why but whenever I connect my Purple El wire to the arduino and press ON button on the app it turns on then I unplug it and plug it to my other El wire which is orange or blue then press the ON button and it does not work. I am using the same lenght of el wire for both but it does not work. Any idea why? If you guys want pics or anything let me know i provide. In the picture you can see what my connection looks like. same connection turns purple on but doesn't turn orange on (Orange el wire works i tested it with another controller just doesn't work with my Arduino)

here is a link to the images orange el wire and purple el wire (same set up) but orange doesn't turn on - Album on Imgur
