hay +‎  wire The original meaning of 'likely to become tangled unpredictably or unusably, or fall apart', as though only bound with the kind of soft, springy wire used to bind hay bales  [1] comes from usage in New England lumber camps circa 1905 where haywire outfit became the common term to refer to  slap-dash collections of logging tools. To go haywire has since evolved to represent the act of falling apart or behaving unpredictably, as would wire spooled under tension springing 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."

haywire (n.)

"soft wire for binding bales of hay," by 1891, from hay + wire (n.). Adjective meaning "poorly equipped, makeshift" is 1905, American English, from the sense of something held together only with haywire, particularly said to be from use of the stuff in New England lumber camps for jury-rigging and makeshift purposes, so that hay wire outfit became the "contemptuous term for loggers with poor logging equipment" [Bryant, "Logging," 1913]. Its springy, uncontrollable quality led to the sense in go haywire (by 1915).
