Ignition wires

I have a question about installing ignition wires on dyna coils. The wires came with these things that lok like they need to be crimped on to the wires so that they'll plug into the coils. My question is, how much do I strip off the wires before I crimp these on? Just to the first bit of wire? Prolly a dumb question, but prolly easily screwed up, and it'll be my first time installing coils. Thanks.

You should only need to strip off the insulation to reveal the center wire, and only long enough so that when folded back over it that it doesn't stick out past the crimped connection.
