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.

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 chose EI because they offer a] certified replacement vs. back-up only and they look great.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Simple and Easy.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!
This is the second product purchased and I am completely satisfied.
Sharp-looking gauges. [I chose EI because of your] reputation.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
Haven’t used it yet, but we are excited to & Love the way it looks!!
