2007 GMC Yukon Passenger side lighting not working after LED install

[Joshua609]

Hey boys got an issue here, I just installed new LED tail lights and headlights and third brake light on my 2007 GMC Yukon and having major issues. I installed the taillights and 3rd break light with no issues, they worked great. Installed the first headlight, no issues get to the passenger headlight and the running light doesn’t work, ok probably the light right? Well I installed the old light back and it’s now doing the same thing. Hmmm go back to the new light inspected the wiring and installed it again, still doesn’t work. Alright I’ll just order a new one. Walk to the back of the truck now the running light/ brake light on passenger side and 3rd brake light not working. I replaced every fuse I could possibly find related to the lighting somebody please shed some guidance

Update #1: Brake lights work, it has to be the passenger running lights. I bypassed fuse #26 and she started smokin so I believe I have a short, anyone have a good place to look?

I would start with the wire harness and connector that connects to the passenger side lights, since the problem was not there before you started this project.
