Looking for a wiring diagram to 1) try wiring up my existing in-hull
transducer to see if it will work instead of installing the transom mounted
unit supplied and 2) wire into my autohelm auto pilot. Any suggestions on
where I can source the diagrams?

Garmin's depth transducers are made by Airmar - I found transducer
wiring diagrams on the Airmar website.

The Garmin 238 manual should identify which wire is the NMEA-0183
output (probably blue, if it is like my 168). If your autopilot has
NMEA-0183 input, you connect the Garmin out to the pilot +in, and the
pilot -in to ground. If the pilot only has SeaTalk, you will need to
get an NMEA-SeaTalk interface from Raymarine.

See http://vancouver-webpages.com/peter/seaspray_nmea.pdf for the
NMEA-0183 wiring on my boat.

Go to the Garmin website. You should be able to find the manual for your
unit there. I have .pdf manuals from their site for every piece of their
equipment I've ever installed.

Andy, thanks for your reply. I have downloaded the manual from the website,
but it does not have the wiring diagram for connection of the transducers!!.
The Airmar website was most helpful - wiring diagrams for every transducer
ever made (by Airmar).

Thanks Peter, your advice was sound - I found everything I needed - except a
supplier of the plug that connects the transducer to the Garmin Sounder
(6F-Airmar) - any idea who distributes these plugs? Tried Bias Boating
(Australia) but they say no body supplies these plugs?

The connectors are Switchcraft EN3 series or Conxall Mini-Con-X, if I
recall correctly. In North America, they are available from Digi-Key.
