While Ethernet cables now come in all sorts of hues, their OG coloring was all bright and flashy in wild yellow. Unlike the thin, flexible cabling used today, early Ethernet ran over thick coaxial cable that had to be connected using a so-called vampire tap. Making the Ethernet network cable as visually distinct as possible, in the “wild yellow” of the specific 1968 Corvette, served the dual purpose of preventing exactly that kind of accident. The familiar blue or gray twisted-pair cables came later, once coaxial Ethernet with a vampire tap was gradually phased out. For a few years, though, the flashy yellow cable wasn't just a design whim of its creator but there to stop someone from actually drilling into the wrong wire and electrocuting themselves.
