blue wire

( n.)

   [IBM]  Patch wires (esp. 30 AWG gauge) added to circuit boards at the
   factory  to  correct design or fabrication problems. Blue wire is not
   necessarily  blue,  the  term  describes  function rather than color.
   These  may  be  necessary  if  there  hasn't  been time to design and
   qualify  another  board  version.  In Great Britain this can be bodge
   wire,  after  mainstream  slang  bodge  for a clumsy improvisation or
   sloppy job of work. Compare {purple wire}, {red wire}, {yellow wire},
   {pink wire}.
