Lowrance Elite Wiring - How to cap unused wires

I have an elite 5 hdi, but I am using the power cable from a 4x without navigation.

Very clever.  I wouldn't have thought of making that swap.

Most hardware stores carry "liquid electrical tape". Just coat the ends and let it dry, very durable and made for wiring and will handle the heat if used on live wires as well. I would coat any exposed connections etc.
 I use it on my power cords at work, I can drag them through the mud and water without tripping the GFCI.

Yes, I have some.  Didn't seem excessive enough for me at the time, but I still have 4 inches of NMEA cable hanging down... more than enough to start over!

Thank you.

I cut the wires at on the diagonal, so none are the same length, dipped the ends in a blob of Goop, put an overly long piece of heat-shrink on them, bent the excess heat shrink back over the wires and smeared Goop on it, then put another piece of heat shrink over it all.

Looks like I did the same, without all of the extra goop.  Did mine last spring, hadn't given it any extra thought since then.  You should be good to go!

I think so, too, Sam, but there are some very ingenious methods being posted - and there's another kayak out in the garage that will need a fish-finder by Summertime...

I cut the cable, put a piece of electrical tape over the end, then used heat shrink tubing to seal it up. Just to be sure, I added a second layer.

I've been using this method for years and works amazing. I usually let it dry one or two times and repeat. It leaves a nice watertight soft plastic cap covering the wires I don't need.
