How to get power to a 360
I recently purchased a used Himminbird 360 transducer from a fellow on line. Being under the impression that all 360 transducers where Mega Imaging I failed to ask if it was. The sticker with the serial number on it has been bleached out by the sun so I have no way of knowing if it's mega or not. I haven't mounted it on the boat yet so I guess I'll have to try it out and see. There are two cables coming from the transducer. I know the one with the metal end goes to my Ethernet switch box, and the other is for power. I just spent 15 minutes on the computer with Humminbird and I could never get the tech guy to understand my question. The power cable has a round plastic end with three pins on it and I need to know how do I hook it up to my 12 volt supply in the boat. I would think I need an adapter cable to transition from the round plug end to my wiring in the boat. Any help will be appreciated.
