No brake lights but my cargo brake light works???

Checked my ground an it was just a little dirty so cleaned it up still nothing.
Running an auxiliary from the negative terminal? How exactly do I do that? Thanks ya'll

Just a long aasss wire from the negative terminal, down the frame to the tail light harness and tap into the ground.
