    Mounting my ELT behind my seat and don't need the 20ft of cord that comes with the kit. Anybody know if a 6ft phone cord will work?

    The ELT manual describes the pinout of that wire. The ELT connects identical pins of each plug together. Telephones reverse them (1 to 4, 2 to 3, etc.). You could buy a short phone cable, but you'll need to remove one plug and crimp on a new one upside-down from the original one. It won't save you anything over shortening your current ELT cable since you'll still need a crimping tool and a new plug.

    Your local network guy would have all said crimpers to do the job

    Sounds scary to me. Using a telephone type cable in an aircraft.

    How long will it last in that environment?

    See page 18 at this link for all you will ever need to know about the wiring used:

    It still doesn't say how reliable those connectors are with all the vibration in an aircraft.

    This snip is from page 18 in the manual:

    Huh? If you turn the connector on the table upside down, then it won't go into the connector on the equipment. The connectors only go in one way.

    And what gives you the impression the material is different from the one AK uses. Because it is used on an aircraft does not make it special. I have inspected both connectors and couldn't tell the difference.

    Used this model of ELT on two different aircraft. Put 175 hours on the first one and have currently 136 hours on this aircraft. Never had a probem with the cable or connectors. I've known a few other builders that have used this model of ELT and don't ever recall a complaint from any of them.

    When the instructions mention flipping one end over they are referring to removing a connector, flipping it over, and reattaching it. A fellow builder (with a tool) shortened the cable I have now and it was quick work. Has not given me any trouble at all. Of course all of this gets tested at every annual.

    Then they should say to remove the connector and reinstall it.

    Still, as a general rule, I do not like crimp connections. Unless you have a proper (a couple hundred dollars) tool and someone that knows how to use it, they can be notoriously unreliable.
