My starter died on me and I changed it out. When I was done and put the negative battery connector on, it started to smoke so right away I knew something was wrong. So I look at the grounds that I know of and they look fine. So I re watch the robertdiy video and noticed that he only had 3 connectors for his starter and I have 4... I've been looking at pictures and I seem to have an extra connector? 3 big red wires and one small one and the green one Can anyone tell me what's going on here and what to do, thank you.

 

I would have been comfortable with that. I think those three belong on there.
