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.

This is the second product purchased and I am completely satisfied.
Great product. So easy to read compared to the originals.
Excellent customer service. Without a doubt the best aviation part I have purchased.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
All looks very nice. [I chose E.I. because of] previous experience.
Your products always work great! Great customer service and a quality product that we have used for years.
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
The layout and quality is impressive.
Awesome Product! Great product and fantastic support!
Installation went great. The Fuel Flow is dead on.
Why did you choose our products over the competition? Complete kit and ease of installation.
