My brake lights don't work. my headlights don't work unless wired directly top my car battery. my third brake light does not either, what could be the problem? is there a wire diagram online or how should I address this issue?

Hi,

There are a few fuses that are connected with the lighting. I attached all the wiring schematics related to the wiring that I have. I highlighted the fuses to check. In addition to checking the fuses, make sure there is power to the fuses as well.
