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.

Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
My mechanic said that your product was very good, and he was correct.
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
[Customer service] is great!
Phone service for ordering was quick and easy. Shipping was quick.
The tach looks and operates amazing. Extremely accurate.
Awesome Product! Great product and fantastic support!
