Take a light tester and check the pins at the truck side trailer plug. With the truck set for running lights check for power at the pins. If there is power then there is a loose or bad wire on the trailer side. If there is no power then there is a power problem on the truck side.
Check for a bad ground
It is for the trailer running lights.
If the blinkers work then your taillight wiring is bad.
Lights are required on a boat trailer to proven those from behind running into your boat trailer. This is especially important at dark where it is difficult to see an unlit trailer.
check fuses under dash panel and for short if wired for trailer
That's called a "bobtail".

shove boards under the front of each trailer tire. as you pull the trailer will ride up on the boards and you can pull it out. if the tires are sunk in dig out some of the mud in front of the tires then get the boards in there.
Actually, they don't have a trailer that is specific to each of the parts, but both the parts are included in on trailer (they do however, have more than one trailer). That's all I know, I hope it was helpful.
In my 98 E250 van the fuses that ran blinkers for the trailer are in the front fuse box (engine compartment) turn on your blinkers and use a 12 volt test light poking into the hole on either side of the fuse If you get power on one side and not the other then the fuse is bad. Or just take them out and look at them one by one.
I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.
