How to Remove "Heavy Power" PC253 Wire Connectors

I was redoing ceiling recess lights and discover these wago like connectors. Unfortunately, there are no release levers for reuse. I snipped off and wiggle the solid 12 gauge wires out, but seems the stranded wires are hopelessly locked.

Any small vise clamps, Utility knife, needle nose pliers

The point is to score & ply open the caps. These connectors are extremely small, so it'll be much better to secure down

Go around the edges, score and gently pry open the cap.

Use needle nose pliers, clamp the flat side of clamp away from stuck strands, pull other end with tweezer

Once removed, clean out any loose strands before reinserting cap. Enjoy reusing your connector
