Looking for a 360 power cable

[5 Alive]

Just purchased a used 360 and it didn't come with the male end of the power cable. I'm having trouble finding it new, so can I just clip the female end and hard wire it at the bow? If so what wires will I find. Is it just strait positive and negative? thanks

I called Humminbird best I can remember it was around $40, here is what they sent me.

The power cord has three wires and you only use two of them--- black and red
Don't know what is inside the power cable.
