While hooking up a boat trailor, I lost brake lights, turn signals and emergency flashers. All fuses check good as does the brake switch. We looked for an in-line fuse but could not locate one. If you can help with this one, I'm desparate.

 

Electrical problems are icky.....

(nothing constructive to add, just a general observation )

 

If you want help, you definitely need to post more information.

Year and model would be a good start, along with a more detailed description of what you did and how you left it.

Is the trailer still connected?

Do your headlights still work?

Did you look under the hood for another fuse box?

Post some more info and you'll definitely get help...
