altenator confusion

[waynieZ]

First excuse me if I muck up posting these pictures, I'm trying out Image Shack

I have a question I got this alternator with my LSA connect and cruise kit, it has 3 posts in the connector but the harness came with a 2 pin connector. I read that the new alternators are more like generators in the way they work and that is what is on the tag for the Alt. it says Gen. I'm trying to figure which alternator is supposed to be with my kit. I send an E mail to the dealer I bought it at, but figured I would check here.

Difference in alt to connector.
