HELP !!!! RCA to XLR

I intend to convert my single ended (RCA) cable to balanced (XLR) cable. Anybody have any experience with it. Appreciate for any information provide.
What do you need to know?? I will try to help you. Thanks, Johnny!!!
If you are wanting to do the work yourself, you can hook the ground on your male RCA to pin 3 on your XLR cable and the + (Center) on your male RCA to pin 2 on your XLR cable. Note: You normally would not want hook your components up this way, but if you do not have XLR - XLR this will work for you.
