Fish Finder problem

[hawg boss]

Hi I have a old Eagle Fish Mark 320 fish finder.I need the 5 " screen( old man ) and it always worked great for me.The power cord that plugs into the back of the unit disintegrated and now I have loose wires (female ends ) to plug into the males on the unit and I have no clue what goes where.I don't want to buy a new finder but can't find a wiring schematic or new power cable. The transducer cable is fine. I was thinking of just start plugging wires in where
ever to see what happens but afraid of blowing the ass off the back of my boat . Old man itchin for fishin.


I think I found my replacement cable....to be continued . thank you for reading.
