We now offer a comprehensive kit that includes crimpers and ferrules (20 ga and 24 ga) along with our popular OLC-2 connectors, designed by our engineers with naval brass barrels, a nylon sleeve, and two set screws. This new connection method rivals the strength of gas-tight cold welds, ensuring the most reliable and long-lasting wire connections Electronics International has ever offered for your aircraft engine monitors.

Prepare the Wires: Strip the ends of the wires to the appropriate length.

Crimp the Ferrules: Place the stripped wire ends into the ferrules and use the crimper to secure them.

Insert into OLC-2: Insert the crimped ferrule ends into the OLC-2 connector and tighten the set screws.

Crimp the ferrule.

Snip off any excess wire that may be protruding through the end of the ferrule terminal.

Pull on the crimped ferrule (3 to 4lbs) to ensure that it is firmly attached to the wire.

Insert the crimped ferrule into OLC-2 and tighten with a hex wrench until the hex wrench flexes (3 inches lbs). Repeat on the opposite end to complete your connection.

Pull on wires (3 to 4lbs) to ensure that your connections on both sides of the OLC-2 are firm and secure.
