or any un-crimped AV pins, crimp them onto the wires and don't put the plastic shell for the plug on use heatshrink instead, and then use a tiny patch of heatshrink where the male and female meet to secure them in a manner you can still unhook the wires if you need too(you can see that spot in my photo, it's the white heat shrink).
