Well ... the two AUX males on the RF board are the same and oriented 
identically, so to do what I did automatically put the +12V on the 
shield.    Were my K2 an airplane, it probably would have been 
impossible to cross-connect them, but even that isn't always true.  I 
saw a fly-by-wire fighter aircraft which will remain nameless get a 
goodly way down the runway, start to lift off, do an immediate snap roll 
and "land" inverted.  Someone had managed to get the connectors to the 
pitch and roll gyros crossed.

Yet again I find out there is no substitute for attention to details.
