After the connections is checked strip the one end of the lengthy wire using a wire stripper and clamp it with a ring type crimper and fix it to the battery isolator’s ignition terminal using the socket and ratchet. For grounding run a wire from the ground terminal of the isolator the the ground point on the frame and bolt the wires to ensure a tight connection.

A 4 gauge wire run from the negative terminal on the second battery to the ground source on the frame. A half inch on each side is striped and a battery terminal is crimped using terminal crimpers. The cable is bolted using the same procedure.
