Rear brake

Hello friends am Tom from county durham just bought a vs800 as a project just frame and engine were on bike the rest was in boxes. The last time I had a bike I was 12 ,I'm 49 now .I've messed about with a few cars in my time but this is my first time putting a bike back together. I didn't strip the bike so its going a bit slow ,I'm having a bit trouble with rear brake cable and switch doesn't seem to be in the boxes. The crome rod from the brake pedal is solid and I cannot find a diagram on how it fits onto cable and switch can someone please help

Welcome Tom.
I'm not familiar with the VS but there are a good few owners here that have posted.
