A  wire that is wrapped around the pin and soldered is a very strong connection
In the bottom picture at http://www.luciani.org/eng-notes/ee-notes/noise
I have some wires soldered to K24A pins. Keep in mind that these are only debug
wires that were quickly soldered for testing. If you tin the wire,
wrap it 3/4 turn
around the gold pin and solder the wire you create a very strong connection.
it would take quite a bit of flexing to break the connection. If you
can stain relief
the wire the connection should never break.
