Help a girl with her electricity please?

Thats basically how its done,... a simple wiring loop, from the battery positive around the location and back to the negative,.. where ever you want an appliance [ light bulb etc], you join a `spur`, a wire running off the red wire [ the live wire ],.. and add a fuse between the start of the spur and the socket,.... you can either use a cigaret socket or wire up the lamp as you normally would and add a switch,.. still retaining the fuse though for safety sake
