My brake light worked fine before I did this and Iv`e drawn up a diagram of how the wireing is.
Can someone explain what I need to do to get it to work again?

I had to Ohm the loom because the wireing goes through the frame, so there isn`t any faults.
It`s on a variatronic, if that means something. It doesn`t look like the way i would normally do it.
