Another option is :
1) After locating the bad circuit
2) Wire in an old head light bulb into the fuse location of the suspect circuit
3) Once wired in , move or shake the harness every couple of inches or so until the light comes on.
By wiring the headlight bulb in , it will only come on for a brief moment when the circuit shorts. This will save you from replacing the fuse, while you look for the short.
Once you located the short, make the appropriate repair
