Re: Color Wiring Diagram FINISHED

Which are 12v switched and 12v constant? Is "alternator" constant and "terminal by battery" switched?

Electricity from the alternator and the battery are connected together, and are not switched, they are always on.

There are some circuits that are always on, and some that are switched on with the key in the accessory or on positions, and some that are switched on only when the key is in the on position.

Have a look at the wiring diagram and the wire colors, especially the wires that come from the ignition switch and go to the fuse panel.



The fuse panel back is what you see on the wiring diagram, so it is a mirror image of the front of the panel. Here is a diagram of the front of the fuse panel and what is switched and what is not.
