I have spoken to Minn Kota two times today and Humminbird three times and got a different answer each time and I still don’t know the answer to my question. I have a Terrova with Ilink and am looking for an Ethernet EXTENTION cable to hook to the cable that comes from the TM and goes to my 5 port Ethernet port switch box. The cable I need has a male ( threads on the outside ) of the metal end and a female ( threads on the inside of the screw on metal end. Will someone please tell me what cable extension part number I need?
