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.

People [at EI] were great to work with.
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
Great service for Electronics International. Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.
Incredible customer service.
