what cable for a Lowrance 332c

[Slim]

I moved a 332c unit from one boat to another and add a new LGC-4000 gps unit. The previous boat didn't have a gps in it so now I need a cable to hook up to the network plug from the back of the unit. I bought the adaptor cable that I need to hook up to the new 4000 gps but I didn't have the original cable from the unit to start with. I have been trying to find the cable that I need but all I can find is the power cable with the nema 2000. Anyone know what cable I need and where I can find one.

The cable that I need is a M-0036, so if anyone has one or knows where to get one let me know.
