BMW Repair: Bmw Alternator, alternator, vin number

Question
I'm trying to find a alternator that will fit my 2003 325i.
I can't find one that matches the alternator plug-in wire on the car. The parts stores are not much help. Is the a adapter for this?

Answer
Gary, I don't deal with aftermarket parts. Do you have a Bosch 120/140Amp or Valeo 120/140Amp alternator. You didn't give the VIN number
Complete Alternator 12 31 7 519 620 or 12 31 7 501 599
Try the volatge regulator if you wish
Valeo- 12 31 7 551 153
Bosch- 12 31 7 559 183
