Thread: Am I missing a wire?

I bought a used Humminbird 360 and there are two wires coming out the top. One is a Ethernet cable and the other is a power. The power wire has a end on it like I have not seen but I was expecting just a red and black wire. What do I need to connect to this or can I just cut the end off and tie it into a fuse

I think that mine has three wires.red,black and yellow.it's been awhile since I hooked mine up,but I think that I folded the yellow wire back and taped it up.used a fuse on the red wire and black is ground.
