Have seen this a few times on fords. I'm assuming it only blows when you use the trailer. then the only cause can be a shorted wire somewhere between the trailer connector to the lights at the rear of the trailer or maybe the light assembly is bad. If the problem happens when you have no trailer hooked up then inspect the trunk harness. and wiring under the bumpers. Something 12v got pinched.

    If it only happens when the trailer is hooked up then you have a short in the trailer wiring harness or water got into the light assembly.

I have 2006 f250 super duty, I have running lights on trailer but no turn signals or brake lights. the trail lights all work on my other ford truck.

If indeed you have the wiring correct, brown for run lights, green for right turn and yellow for left turn, and is not working on one trailer but not on the other, ALWAYS go to the ground connection every time. I've wire many a trailer and found that if no lights or only some working, It's always the ground connection. Check this with a pair of jumper cables between a clean spot on the tow chassis to a clean spot on the trailer chassis and turn the lights on and try the signals and brakes. That's the best test to do when checking the system.

I got 2000 f250 that has started blowing fuse 1

I have run into the trailer plug harness and the plugs themselves getting severely corroded cause a back feed issue which will blow fuses as the system is directly tied into the truck lighting system. Check the trailer plugs both the four wire and the seven and see if they are all green. The four wire is usually the the bad one.

I need to find the fuse that feeds the trailer plug on my 2006 f250 super duty, I dont have an owners manual. Please help,

I'll do you one BETTER! Click here and you can download a free copy of the complete owners' manual from the Ford Fleet website... very cool. The fuses are located in the engine compartment fuse box and there should be separate fuses for different lights on the trrailer plug.. one for the left turn, one for running lights etc.. check them all.

When I hook up my horse trailer to my 2003 Ford Excursion, it blows the fuse for the running lights. The blinkers and brake lights work, but that is all. If I change the blown fuse, it will only blow...

fix the plug,car or trailer, and check the wiring and bulb sockets in the trailer
bigger fuses are equal to burnt wiring harness or fires in either vehicle
