If you strip the end of one of the eight tiny wires in it, Is it a solid piece of wire or many little strands wrappe together.
If solid no.
If stranded yes.
The best thing is to wait and buy the premade cables. They will cost less than you can buy the ends and pay for the wire and then it saves time making the cable and worring about weither you did it backwards so that you controller gets damaged when you plug it in.
This is my opinion and only an opinion.
