Powermaster Alternator Wiring Harness Adapters
Powermaster alternator wiring harness adapters are designed to connect the alternator to the vehicle's wiring harness.
When choosing alternators, it is not the year of the engine that controls which alternators can be used; rather, the type of wiring harness the vehicle is equipped with is the limiting factor. For easy installation, Powermaster alternator wiring harnesses adapters include the correct connections for specific alternator styles.
