In my experience, the insulation is too big to go into the connection and the side of the crimp tool keeps it from going in.

I probably need to make a wire ruler and mark exactly how far the wire goes in for each different connector.I was able to crimp 4 connections (in 5 attempts) using your instructions and this crimper (which is a bit cheaper).

This is a crimp tool Digi-Key sells under Adafruit Part Number 350 which can be used to crimp many housing contacts ranging from 20 to 32 AWG wire. Are we supposed to pull the existing pins out of the connectors, and push the newly crimped male pins into the holes?
