Please bear with me for this is my first install I have ever attempted to do. I just recently picked up an Eagle FishEasy 350c fishfinder on & would like to install myself. Going through the install instructions, it all seems fairly straight forward, but I do have one question I need a little help with. For my power connection, I need to get some additional 18 gauge wire with an inline 3 amp fuse for the positive connection. Where can I find this wiring setup? Thanks
