So my truck didn't have a cigarette lighter so I put one in months ago and tested with test light was getting power to the socket so I called her good. Never used it.
Anyway forgot lighter so figured just use the cigarette lighter. Lighter would pop wasn't getting hot.
Took out threw a test light on socket was getting power tried again nothing.
I noticed the bottom courtesy lights under the dash were coming on every time was depressed.
And it ended up blowing the horn fuse as well.
I'm pretty sure that orange wire is for the lighter, all other lights are hooked up.
So I'm a little confused as what's going on.

Well it would seem that the orange wire is not the correct power wire. I can't look for a wiring schematic without knowing year and model so. I just remembered what I can do to see your make and model,so now that Ive looked at that Ill try to find a schematic. On the future your posts shoukd include what you are wirking on. It makes people trying to helps life easier and helps get more accurate information. This is what most if us see on first look at your post.

Looks like it should be orange with a stripe. I believe straight orange goes to headlight switch. @Jgonick is really good at finding accurate wiring diaghrams,me not so much,hopefully he'll read this and pitch in. 1983 k25. I looked up a 75 k25.

I'll do some more digging around see if I missed a wire. That orange wire was just sitting there I assumed that's what it went to
