1985 single cab electrical problems

[true74enduro]

I realize this should go in electrical section I didn't want it to get over looked.

So I have an 85 single cab it has power lock and windows. I have an electrical short in my horn and others that I'm hopping to solve. The other things that don't work are my cig lighter I'd like to have it to charge my cell. I also have a short in my dome light. I when I went to check my some lights bulb to see if it had burnt out, I noticed that it's connecting wires were melted.


Please and thank you to any help that's given.

Oh also I know my horns work as I have a wire hooked to a push button and and hooked to another fuse as when I put a fuse in my horn spot it blows
