Vehicle Compatibility & OE Cross Reference
External Bosch alternator voltage regulator for 12V systems where the alternator uses a matching 3 terminal external regulator setup and the original unit cross references to the OE numbers below. This type is used across a wide range of passenger, commercial, and agricultural applications, so final matching should be done by regulator layout and OE number, not only by vehicle name.
