I purchased a very large order of my first RGB's from Ray Wu. 30x Strings, 20x strips. When they arrived, they all have one female plug on one end, and a male on the other. I only wanted one end to have a plug (male) Does any know if there is an easy way of fixing this? preferably without having to cut wires etc. Ideally, it would be good if they sell screw on caps, so I can just put caps on the female end. Does anyone know if they exist, and where I can get them?
