Basic DIY 12V Wiring | Fuses, Wire Sizing

Doing your own 12V wiring can be rewarding, if you do it right! I show how I choose the gauge of wire, fuse size, how to run cables and do everything to make a basic 12 Volt circuit. For this video I install a marine radio, echosounder, bilge pump and accessory power in the boat. A fairly simple project to get your head around how to do your own basic 12V wiring.
