Electrical short

EH41867 last 7 digits of the VIN.
hi, I got a problem I got a short in the electrial system somewhere. Its the right side front and back lights, by that I mean the front right yellow light but not the blinker(the blinker works) and the back right light(its not the brake light but the light thats stays on when you turn on the lights). I tried replacing the fuse with the correct one(10) but it would just burn or sometime they would stay on for a min. Or two. I replaced both front and back bulbs and I checked the connectors they are fine not dirty or broken. I took the harness out and looked at the wire that where visable and there where 2 wires touching each other that had insulation damage so I put electrical tape around each wire, but that still didnt work I figure there has to be another one. Am I going to have to trace the wire back to the fuse box or can I do something else? I got a multi-meter but no clue how I would use it to fix it.
