Agree 100% with Eddie on how that bolt would have looked when it left the factory.

As to when that happened in the assembly process (on 65-67 Chevelles at least), that harness was installed on the engine as part of the engine / transmission dress work (while pullies, brackets, coil, plug wires, etc., were being put on), so it was on the engine before the engine was ever installed on the frame. That way, after body drop all they had to do was take the fuse block end of the harness over to the fuse block and plug it in.

Same goes for the 4-speed backup light switch harness, or the TH400 kickdown harness, when so equipped.

Much easier than installing those harnesses to the engine after the body was already in the way.
