Default URGENT.. Alternator wiring question

I just did the lower intake manifold gasket repair. I am to the point of hooking up the alternator. I have the sealed connector in place. I have one red wire coming from the positive battery cable, and a set of two black wires coming from a harness in the back of the motor. Which ones hooks to the bolt on the back of the alternator? As I have it now, I have the red attached to the bolt, and the two blacks attached as a ground to the alt bracket. I cannot find ANYTHING online about the wiring...

Thanks!

Well, on my blazer when I put in an AD244 high output alternator, the red wire from the positive of the battery went to the bolt on the back of the alternator. Black usually means ground anyway.

Oh and not to be a smart@$$ Gary, but he IS posting it in the blazer/s10 section, so he might be working on a blazer or S10?
