Okay, well hooked a trailer up tonight and everyone was driving by flipping me off and stuff. Im a pretty aggressive driver so I thought I just had a cool truck and drove badass and everyone wanted to be me. Wrong.

So I get to the house and see that my trailer running lights are on, and my truck running lights. But guess what? Brake lights dont work AND only my driver side reverse light is working. What is going on?

I would think fuse but I have that one reverse light working. What is going on guys? What fuse would it even be? an IOD fuse or something???

 

Harness is wired wrong on the trailer or your truck? Seems right since you had no prob without the trailer before right?

 

well after checking the lights and fuses, I reset my PCM. I think you are right and my trailer is having some wiring problems and shorting something out. I will figure it out after hunting tom

 

Glad I could help, hope you bag the Sag Daddy tomm. Good Hunting!!
