Start by replacing the fuse with a 12 volt light bulb such as a brake light. Then you can unplug things to find which ones make the light go off or dim indicating the short is removed from the circuit.

Do you have a trailer wire harness? Check that make sure it isnt pinched or rubbing on something causing a short to ground.

Like carradiodoc stated, your going to have to make a short checker, get yourself a wiring diagram and start unplugging bulbs etc. circuits/ and anything on that circuit, It is a process of elimination to find a short/ It will take time and testing. Anybody can guess at it, but it is you that is going to have to do the testing. I cant locate a good diagram for you, maybe one of the other guys can find or post one.
