Help I have an wiring issue

So I drove my Plymouth across town last night and someone yelled to me and said I had no tail lights or beak like lights. Turns out I don’t have any corner lights either. I have head lights and turn signals. I only have one back turn signal working. The fuse was blown. When I replace it and turn the lights on it blows. I replaced the light switch and that didn’t fix the problem. Looked all over and can’t see any damaged or broken wire. I unhooked the light harness from the back and the fuse still blew. Would it be in the fuse box? Or maybe turn signal switch? I’m not that good at wiring. Anything would be helpful thanks.
