I'm having trouble figuring out what exactly you are saying. There are fuses for each individual wire, yes.

Check for continuity through the connector behind the driver's side rear fender well. I had to run jumpers over mine, as the connector has gone bad on some parts.

There's a 20Amp mini-blade fuse that poped on me that powered the marker lights etc.. when the headlights were turned on. Its in the fuse block under the hood. The row of fuses closest to the fender next to the horn fuse. I swapped it out with the horn fuse, also 20A but killed the cruise control in the steering wheel. Either way it sounds like you have something shorting on the trailer or harness.
