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.

Great tech support. Someone always answers and gives accurate concise information.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
Easy installation.
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
Simple and Easy.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
We have other EI products currently and have always been satisfied.
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.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
