need advice for electrical install

[goofyexponent]

Hello all,
I recently purchased a 2012 grizzly 1648 open, I love the boat and need to get some lights installed and my fish finder. What I'd like to do is mount a battery in the back corner and run it to a fused 4 switch panel, and mount my fish finder right above it. I'm just curious if people with similar rigs can post up some pictures of what you did and how you routed wires?
Thank you in advance

Is your boat a tiller, side console or center console?
If your boat is a tiller I can send some pics of my side cedar wooden console I built for my GPS, fish finder and lights and bilge pump switches.
