Rewiring advice needed.

[Briguy]

My CC looks like a big birds nest inside with about 30+ wires going into about 8 fuses. I've got a stereo, vhf, radar, 2 bilge pumps, 2 gps units, 3 batteries, running lights, spotlight, baitwell, cigarette lighter, anchor light, compass,Garmin blackbox sounder, sitex sounder, fuel and hour guage.....that's all I can think of for now.

Are there any good websites or books to help guide me on cleaning up my mess? Thanks! Brian
