My ELT showed up yesterday from Gulf Coast Avionics. I drilled the mounting plate to the shelf and installed nutplates so the mounting plate can be removed in the future if necessary. There are three connections necessary for the ELT: a telephone cable that connects the ELT to the audio alert box and remote interface, an insulated four-conductor wire for power, ground, and GPS serial input, and the antenna cable.
I connected the telephone wire and snaked the other end through the conduit and up behind the panel. I had to cut the RJ12 connector off of the end so that it would fit through the conduit, but that just gave me an excuse to buy another tool so that I could crimp a new connector on the other end after I was done :-). Even if I hadn’t needed to cut the end off to route the wire, I would probably have done so anyway so that I can make the wire the exact length necessary instead of coiling up the extra wire.
