My brake lights doesn't work any more, my turn signal doesn't work. When I turn on the headlights, the passenger turn signal lights up in the rear and on my cluster. I swap the entire chassis harness off my old shell which is known to work, and still the same thing.

 

Sounds like the rear ground wire is disconnected or broken.

 

I tried and reground it thru the chassis itself from the two tail light side and still nothing.

 

What is "it"? Post pictures.

 

Where can this rear ground wire be found? I also have an issue with my brake lights on my EG

 

 

Also verify the correct bulb types are installed.

 

Ok I found the problem on mine, the tail light harness big plug that plugs into the big plug for the chassis harness was not in the same pins. I had to re-pin it. Its the plug that sits at the rear driver quarter panel.
