[BC] Breaking out 8723 to Two Connectors...

[Burt I. Weiner]

That's exactly what I do with the exception that I use white/green as 
the left pair since red has commonly been used as a right channel 
indicator.  I also slip a piece of green colored bark over the drain 
wire going to the right channel connector.  The white lead is + while 
the green lead is -.  For the right pair, the red is + and the black 
is -.  I use a super-fine Pilot marker pen to write on the cable 
itself where it goes to or what it is.

This method is fast, clean and I don't see where there's any 
waste.  Yes it does look a bit odd but so what.  It'll probably 
outlast splitting the pairs and using shrink-fit.
