Helping out my neighbor with his boat.... It has two new(2024) Suzuki DF300s that replaced a pair of aging DF225. The new engine upgrade also included the fly by wire for steering, shifting, throttle, etc. What a great system!!!
But here is the question. On the previous DF225 the SDS connector was right in the front and had a cap. I simply removed the cap and installed the SDS cable leading to my PC.
On these new DF300's I can't seem to find the SDS connector.

Suzuki has made available their service manuals and they suggest the location of the connector (see attached drawing). But rather than a cap, it seems to have a wire that routes through the plastic tube with other gas, electric, etc going into the boat itself.

Does anyone know if this is in fact the SDS connector? And whether I can disconnect it there and temporally connect my SDS cable and PC? We would like the ability to see the logged ECM errors if we have problems.

Thanks in advance for any guidance

The CAN connection to the ECM is typically a small, square 4 pin connector with a cap like that displayed in the diagram

Need a CAN sniffer or a interface module to collect the data
