I'll start by saying my knowledge of automotive electrical is limited to when I instaled an ignition switch in a 68' Ford (in 1984). With that said I have a pic of my fuse box.

When I opened it I noticed that the PO had a couple of wires in there. I traced them and they lead to a toggle switch which is for the custom fog lights. Is this a normal way of doing this, I have never seen wires inside the fuse box on any car before. The plan is to get rid of the lights anyway. Also, form the look of the box would you say a new one would be a good investment?
I'm trying to figure out why I have no tail ligths or turn signals so I am starting with the fuses and bulbs. Should I attempt the electrical restoration or should I have an expert do it? Any advice would be great.
Thanks Pesto
