AC clutch clicks when battery reconnected.

[tnt4him]

I removed and reinstalled my engine on my 2005 Aveo. Just about at the finish line connecting the battery when I noticed putting the negative cable on the battery the AC clutch clicks and the radiator fan comes on (key off) I know that this is not right and the only hesitation I had during reassembly was the starter connections. The two large copper post each take a a similar large black wire and by the shape of the fish eye connections I installed them. One had a curve ending so that went in the curved top and the other was square shaped so that went in the bottom square part of the starter. There was also a bare ground wire that mounted on the starter mounting bolt. And I did not forget the small wire on the backside. I have not started the car because if my connections are not right I could do some serious damage. Any thoughts or experience on this?
