Calling electric gurus, help!

I did try to build a truth table, that is how I figured out the wires that I did,
And that was excellent advice, I did not ignore it, but I could only figure so much out maybe because there currently isnt a brake lite switch wire there? I can not look up the factory service manual because I dont know what year and modle it came from, any way I'm close, I think I'm missing a ground.
