Do a nice tug on the metal end and the cable in opposite directions to make sure that ti is securely fastened and crimped together.

You then want to disassemble a female MC4 connector by unscrewing the end cap. Then you want to insert the end cap, strain relief, and compression sleeve into the wire. You then want to slide the female MC4 connector into the body of the male metal pin until you feel and hear a clicking sound. Finally, go ahead and screw the end cap onto the end of the female MC4 connector.

Crimp-on the female metal end to the copper exposed wire using your ratcheting tool. Unscrew the male MC4 connector and slide the end cap, strain relief, and compressions sleeve into the male metal end attached cable. Add the male MC4 connector and screw the bottom cap in place.
