Product Overview
How It Works

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.

Nice bright display.
Great product at a great price …. (and) reliability.
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.

Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
