Wrong Harness / Alternator or BOTH?

The new one looks like this and does not have a 'power wire' or 'batt' wire. (I realize that the ground wire is on the batt terminal in this pic and that that is wrong)

My new alternator has a single post labeled "Batt" which is what I assume my old harness's capped wire would have bolted to. Am I missing my batt charge wire with this new harness? If so is it as simple as running a wire from this directly to the battery and calling it a day?
Thanks for any help here!
