I am unsure of which fishfinder unit This particular 12 V power cable is made for? It is definitely an older cable most likely hummingbirds, Lowrance, Eagle, Ray marine, simrad? Or maybe another company? Sonars fish finder, flasher etc. cable is Good working condition. Does this place in the cabling? I believe the sugar up is factory it may be fusible link? I may be a surprise. It was w as it looks good (pictured). Cable is 3 feet long
