My
boat has an old
depth finder that reads out on the traditional dial over the
companionway hatch that is hard to read at night. I installed a second
transducer to read through the
hull for attachment to my older
Garmin because it is easier to see at night. It turned out that I needed to get a different
power cord/wiring harness for the
Garmin that had a socket to
plug in the
transducer. I discovered that the present harness instead has a socket that fits a
plug that runs to an external
GPS antenna in a
puck on the rail. In other words, I have two harnesses, one that plugs into the
antenna and the other that plugs into the transducer, and in both cases there are also some extra color-coded wires left hanging loose. I would be able to either hard wire those or attach them to my own connecting plugs. Garmin support was not entirely helpful. My questions are these:
1) The
GPS seems to
work fine with the external antenna disconnected -- is there any advantage to keeping it?
2) Am I right in assuming that I could use the loose wires on either harness to connect the device that doesn't have a matching plug, that is, either the external antenna or the transducer?
3) Is it likely that the color coding on the Garmin harness is matched by the color coding on either the antenna or the transducer?
Thanks
