I am planning on eventually putting a 788 HD DI on the bow & link it with my new 998 on the console. I have been look'n at the cables & was wondering what I'll need. 15' of cable would be plenty. Will the Humminbird AS EC 15E Ethernet Cable - 720073-5 work & will I still need the adapter cable for the 788. On all the pictures I've seen the ends on the Humminbird AS EC 15E Ethernet Cable - 720073-5 look different from the other Ethernet cables.
