The OLC-2 eliminates the need for soldering, crimps, and expensive connectors, all while creating a perfect connection between two wires. The two wires are stripped 5/16″ and then slid into opposing ends of the OLC-2. A set screw on each side of the OLC-2 is gently tightened. The OLC-2 can also be used to create perfect connections with Thermocouple wire, which means no more bulky TC connections.

After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
Very easy to install and directions were straight-forward.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Your products always work great! Great customer service and a quality product that we have used for years.
Excellent tech help…
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Great tech support. Someone always answers and gives accurate concise information.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
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.
