Derek Gaston, Archie Campbell, Tony Wallace and Aidan Fulton all started and were watched by Ton's full first-team squad after they were told to attend following the defeat at Annan the previous day.
Dylan McLaughlin gave David Hopkin's side a sixth-minute lead when he collected Fulton's low cross at the far post and fired high into the net. The lead lasted just three minutes, however, and it was star man Connick who levelled things up, dispatching a fine penalty past fellow goalkeeper Derek Gaston. Experienced frontman Andy Monaghan then evaded a Nicky Jamieson challenge and rounded Gaston before slotting home number two.
The Largs line-up included five former Ton players in William Boyd, Craig Black, Creag Little, Kevin Struthers, and Scott Keogh, who made it three with a glancing header from a Gus Gault corner.
But the introductions of substitutes David McNeil, Jordan Cairnie, Ryan Hirooka, pictured, and Cameron O'Neil turned the encounter back in the visitors' favour and they drew level in the space of 60 seconds.
The impressive McNeil was the provider on both occasions, rolling the ball to Cairnie for a tap-in on 67 minutes before teeing up trialist Hirooka for the equaliser shortly afterwards.
Wideman McLaughlin wasted an opportunity to give Ton the lead when he blazed a spot-kick over the top, but there was still time for 16-year-old midfielder Cameron O'Neil to seal the win with a stunning, late strike.
