My issue started about 2 weeks ago when suddenly my tail lights fuse #4 weren't working so I changed the fuse and went about my business. After that I started popping my turn signal fuse #16 along with that. About a week after that I was parked and was unable to put it into gear and after using the message boards figured out it was the horn/stop fuse. I have been replacing fuses left and right for the last 2 weeks and put a 20a fuse so I could drive and be legal till the weather warmed up. Everything was fine until yesterday when I started to smell an electrical smell so I got the truck home and started to research..... I found a post about aftermarket trailer harness being an issue so I disconnected my set up and hooked back into the factory and now I am popping my small fuse #4 15a immediately. If someone can point me in the right direction it would be GREATLY appreaciated!
