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.

[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
It works very well; easy operation.
Simple and Easy.
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.
Great product, frees up space
