[ARC5] Large-Pin GF/RU etc. Connectors

The best thing that I have found to use to install the push-button springs 
in the large banana pin connectors is another push-button spring opened up 
to about a 20 degree angle.  I keep one hanging behind the work bench on a 
ground buss wire that happens to run along there.  I've found that with the 
installer spring holding the operating spring in place, one can hold the 
connector body in the left hand with the left index finger pressing down on the 
installer.  The right hand pushes the insert with wires into the connector 
body far enough so that when the installer is pulled out, the operating spring 
is securely captured.
