Re: Help! Electrically challenged..
To help you a bit, think of electricity like water flowing through a pipe. It has a source (a bucket, a well, a water tower, etc), flows through a pipe to a house where it branches out to other things like front of house faucet, back of house faucet, kitchen taps, bathroom taps, etc. To turn the flow on and off you need valves. Electrical switches are akin to the faucets in a water system. So -- electricity flows from the soure which is the fuse panel for your purposes, but the actual source of power is the battery. From the fuse panel, current flows through a fuse to whatever switch you want to control whatever device you have in mind. Swiches are ON/OFF devices and function very simply like cutting the wire. OFF = open circuit hence no current can flow. ON = closed circuit so current can flow to the device. At the device current flows through the bulb (a light) and back to the battery via the ground wire. You NEVER put a switch in a ground wire. Here is a diagram of a complete circuit -- which in this case is a simple light.
The only switch that differs from this is wiring for the Nav/Anc lights. These are wired with two different types of switches. For your purposes I suggest this one. It is a simple ON-OFF-ON switch. Both the switch and diode are available at Radio Shack.
