Need alternator wiring help Please.

Hey all,
I need some assistance with a wiring problem. I needed to replace the internal regulated 3 wire alternator with a new one. the one I got from summit has a different plug on it. i figured no problem, I will change out the plug and wire it up the same way. I went out there this morning and the car was dead. Obviously it doesn't wire the same. Can you take a look and tell me where I went wrong. The flatter white plug is what was originally on the car, with the flatter alternator. The squarer plug is what is on there now. Where did the wiring go wrong? The battery was perfect before changing the alternator. The bearing was going out on the previous alternator, that is why it was replaced, It was still charging fine. Thanks in advance.
