Indeed.  Thanks Charles.  And, the nice thing is that the wire it comes with
is 12 Ga. 4 conductor, very flexible.  That is hard wire to find.  12/3 is
easy.  12/4 is not.

One comment.  These connectors are available with rectangular or round
flanges (NL4MPR I think).  I much prefer the round flanges because they have
considerably more space between the main large hole and the 4 screw holes.
This allows your main hole to be slightly oversized without fear of running
into the small screw holes. The trade off is they take a little more panel
space.

If it matters to anyone, I did set a standard for the connections that I
have used in some custom delivered power supply connections to both
customers and to Paul.  They are as follows:

+1 = +15V
-1 = -15V
+2 = +5V
-2 = GRD

Now, I can hear some people arguing that multiple grounds are required.
But, let me point out that in the MOTM wiring scheme, all grounds become
common at the power supply terminals.  If you keep all the wire between the
power supply and the distribution PCBs short and make it all # 12, you are
effectively at the power supply electrically.  Close enough as I see it.  Of
course, feel free to disagree.  I'm just a Stooge. Those of you following
the Oakley scheme of a separate earth are on your own.  This connector is
also available with 8 pins.
