I have a minn kota terova with us2. I am new to this unit and need help with getting power for my lowrance elite 5 so I can connect to the trolling motor and read the sonar from the front of the boat. I have the adaptor that runs from the trolling motor to the fish finder. From my research on the site it appears I need to run the power from my cranking battery to the adaptor wire to avoid interference. What gauge wire should I use? Also, is it ok to run the wire straight to the fish finder or should I use a fuse somewhere in between. If I am totally wrong! Please give me advice. Thanks
