Probably, that was an old Rev. G TIU that I was working on when I annotated it with the TVS positions. However, you'll notice that the wires are soldered onto the ends, not just secured with nuts like the later versions. The clue is there are no fuses, all the later versions have the 20A fuses.
The only downside of a loose jack in a Rev. G is... a loose jack. It wouldn't affect the actual connection in this version.
