I'm trying to do the big 3 upgrade and confused about my alternator. I only see one wire where I could attach the power cable. I don't know if it is negative or positive?

That's the positive stud. The negative is the whole alternator case that grounds to the bracket that is attached to the engine block.

A DMM goes a long way for stuff like this.
