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.

My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
Keep it up. I’ll keep coming back.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
Easy install.
My mechanic said that your product was very good, and he was correct.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
You folks do a great job. Keep up the good work.
