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.
