hay +‎ wire To go haywire possibly originally referred to the tendency of wire spooled under tension and used in the baling of hay to spring into an unmanageable tangle once a piece had been removed from the factory spool, e.g., "he took off the back of his watch, removed a gear and the whole works went haywire." Or a tendency of slap-dash repairs done with scraps of baling wire to fail catastrophically at times of mechanical stress. Perhaps the meaning of haywire – all in disarray or disrepair – stems from this expression.

      The engineer who makes of his calling a burden, who sees nothing but the wrong, or imposition as he may term it, who fancies perhaps that the whole world has conspired against him, who commences to damn things as soon as he appears upon the scene of his labors, and continues to damn everything, including his train crew, the engine, the officers, and almost everything, animate and inanimate, while making the round trip, is working out his own destiny, and it is but charitable to say of such a man that he is not well, his digestion has gone " hay wire " as it were.
