To install a crimp-on connector, strip the wire coating off of the wire to expose about 1/4 inch of wire (if you are using a large connector, more than a 1/4 inch may be needed). If the wire is stranded, twist it to ensure that no stray strands protrude. Unstranded wire (solid core wire) should be soldered because crimping usually cannot assure a tight enough grip on the wire.
If the connector has a plastic cover, slip it onto the wire first. Next, insert the wire into the opening on the connector. With a pair of needle-nose pliers crimp one side of the metal housing, then crimp down the other side. Crimping both sides at the same time will probably result in a poor grip and allow the wire to come loose.
