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.

Incredible customer service.
Excellent installation instructions [&] recommend[ed] by others.
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.
Your products always work great! Great customer service and a quality product that we have used for years.
Great tech support. Someone always answers and gives accurate concise information.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
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!
My mechanic said that your product was very good, and he was correct.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
