Here's a nifty way to make wires easily connect
The right crimps can also make your electrical connections less prone to short.
Step 1: Braid the Wire
Strip the insulation off the wires if you haven't already.
Take the exposed end, and twist it between your fingers until the wires are all wound in a helix.
This just makes them stay together until you can attach the crimp.
Step 2: Insert Into Crimp
Put the wire into the crimp until it gets to a metal tab.
Step 3: Crimp!
Grab the crimp in your crimping tool. Put the seam side up under the nub on the crimper, so that they get pushed inwards and apart when you clamp the crimper. Clamp down over the plastic
Grip moderately hard, and maybe do this a few times.
You want the wire to be unable to come pull of the crimp, if you lightly tug.
