Few potential pointers:
Initially, expose more length than you’ll need. I usually do 1 inch / 2cm
Untwist your pairs and get them loosely arranged
Pinch all the wires flat and arranged between the side of your forefinger and your thumb. Bend them back and forth, up and down, side to side, and generally “massage” them - being sure to keep them arranged - to get the kinks out. They’ll straighten out and you’ll form a new wire “memory” in your intended arrangement.
You can then cut the ends flush with one another at the intended length and you’ll have a much easier time threading them into the connector.
