One night driving my car just dies... so i pop the hood and look around and see a split wire from the starter. I looked like it was either already cut and was barely held on or it had melted... so i manage to stick one hand down there against the hot ass manifolds... and was able to twist the crappy wire ends together and wrap some electrical tape around it...

Question is what is that wire called? I think it was red. Starter wire? Positive wire?
Also where could I find one? General auto parts store?
And how hard would it to be to replace? What all is involved?

Thanks
