horn issue

Thanks for the input, here are a couple of pictures of what I have. But I think I have bigger issues as I was trying to trouble shoot the horn issue I notice that with the headlights on and I turn on the right turn signal it will not work, but with the headlights off it works fine the left side works either way. So now I'm not sure what I got going on.
I think it might be a ground issue but I have a one ground wire screwed to the bottom of the dash how many grounds should I have?
