Tony, I figured the RCI mic would be 6 wire, but it's not. I thought I was the one that put the 4 pin plug on it, but it looks like it came that way from the factory. So I can either go by the electronics shop and get some 6 wire mic cord, otherwise the only thing I have is plenty of Cat 5 cable, which is unshielded so I don't think I should use that. Or, if someone has a 6 wire junk mic, I have the 8 pin connector already...
