Can a Garmin P79 support a Raymarine DSM300?

I’ve been busy integrating older raymarine electronics on my new to me boat. There are three transducers installed ne I have succeeded in activating on a preexisting Garmin N2K network to a GMI10 display. The other is a P79 (I believe) and I’d like to hook it up to the already installed DSM300 to display on a C120 MFD-Is that possible? Picture attached of the Garmin cable to the transducer and the DSM300 cable to the sounder.

Pretty sure we had a DM300 with a P97 transducer for a while, though it had a RM plug on it. Data went to a C80, now long gone.

Today we have the ST60 forward of the mast step and a Garmin P97 in the cockpit locker. Neither interferes with each other due to the distance and different frequencies I think.

You might have a problem or might not, too many variables to say for sure. Connect up the P97 and put the sender in a plastic bag and lay it in the hull as a temporary measure. Assuming you are in the water, fire up both senders and see what happens.

Airmar provides the wiring diagram for the ducer on their website (seems they made it for Raymarine) so theoretically I should be able to pair that with the wiring schematic in the sounder manual and forgo buying a new transducer when this one is perfectly servicable. Any suggestions where to get a DIY connector? I’m an electronics newbie but want to become more self proficient. I can buy a new transducer with cable for $195 including the cable and connector, but the old one is in place and the cable already strung-just need to change over from a garmin connector to a raymarine DSM style connector and reconnect the wiring in the correct order. Is it really that simple?
