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.

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.
Phone service for ordering was quick and easy. Shipping was quick.
Excellent installation instructions [&] recommend[ed] by others.

[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, 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.
