Ok, I have a problem. Today I was wiring up my boat trailer, and I was testing out the wires, and everything looked good. Then all of the lights went out, and I can't get any current from my trailer plug in. I am pretty sure that it is a fuse that is blown. I just don't know how to find out which one it is. Please help me out because I was planning on putting my boat in this weekend.

 

I believe there is a seperate fuse box for the trailer lights behind the main fuse box under the hood. I'll check my truck and manual a little later and let you know more.

Good luck,

 

I have a 97 XLT and had the same problem. Besides the fuse box in the cab by the driver's door there should also be some fuse boxes under the hood near the cab on the driver's side. Your owners manual should tell exactly which ones deal with the trailer lights. In mine there were fuses in both the cab and under the hood that controlled the lights.
