Trailer tail lights

[bigo1966]

Is there a seperate fuse for my passenger side trailer turn/brake light? I dont have the original manual and all the fuses "look" good. The brake light works on the truck but nothing on the trailer. I traced back as far as I can being dark and only having a flashlight but nothing is making sence. I cant imagin the factory ford wiring harness just going out over night.

Why does this stuff always happen just before a road trip?

I don't know, but it happens to me too. I think it's just trailers. They never work.

Another thread says it's fuses 6 and 7 in the box under the hood. Don't know if the years are the same.

That would be sweet if you could take a quick look.

Yep, 7.5 amp fuse under the hood. #3

yup #1 and 3 under the hood both have to do with trailer lighting
