This is a Bosch 120 amp alternator. It can be found on many GM cars from 2006-2009 with 3.8L engines. The 2 pin voltage regulator plugs in the back of the alt. This style Bosch has an internal cooling fan. These alternators are known for bearing failure after 150k so if you hear a grinding noise, this may be the culprit.
