Newcomers Llandudno secured a third successive win to go top of the table in their third game of the season, this time condemning 10-man north Wales rivals and fellow new-boys Holywell to defeat.
Kieran Smith put the hosts ahead with Mark Winsdale levelling for the visitors just before the break.
Holywell's Danny Sullivan was sent off in the fifth-minute of first-half added time.
It still took until the 90th minute for Llandudno to go ahead, Mark Cadwallader obliging. Callum Stephens added the third as full-time beckoned.
Holywell might find consolation in rising off the bottom thanks to goal difference as they swapped places with Trefelin.
