Got a new 112 Ultrex (1368820) I'm installing and I have nowhere to connect the Universal Sonar cable. There is an old Lowrance X51 at the bow and Lowrance Gen1 HDS7 + an old Garmin 240 at the console. What is the best way to hide/tie it up? Also, does it matter where I mount the white Heading Sensor puck?(front or back of boat? Thanks to all who reply! Scott
