The new needle set

Ok, I figured it out. There is a little hole that goes through the cable part on both sides. I remember there being a little metal object in the set (along with some stuff I wasn't going to use anyways, some stoppers. That little object fits perfectly in the little hole and the needles tighten up nicely and I have no more problems with the needles loosening up. I wish they had a directions to go with the set. I was having problems also with figuring out the pouches. What goes into what. They had cables and needles but then 3 different sizes of pouches. I guess you can have it any way you want but it would be nice to know what the pouches were intented for.
