You don't, John.  They are insert, heat, solder, which is pretty much 
how all connectors are put together.  It helps to have one of those 
weights with the adjustable test clips on them to hold each wire as you 
solder it into the cup and a vise for the connecter.  If there are no 
wires soldered in the two used cups you can use the heat and stab 
method.  It's odd, but connectors were probably the first instantiation 
of the "solder is strong enough" philosophy that found its culmination 
in the Tektronix scopes, where _nothing_ was wrapped around terminals 
"to make a secure mechanical connection".  Another old wives tale debunked.
