APP connectors can be a real pain if not done absolutely correctly. I ended up purchasing a ratcheting crimper from HRO as I could never get just the right force on the manual one. It was either too weak and the wire would fall out when tugged, or I would mash it too hard, and the contact would not fit in to the plastic housing. The ratcheting crimper is first time, every time, at least for now
