This is a plug and play alternator only Holley Power Tap harness for either the 4 Cavity or 2 Cavity alternator. The 4 Cavity alternator will function as it did in the factory vehicle. The 2 Pin alternator will function in default at about 13.5 volts or so. Choose your alternator type in the dropdown.
BP Automotive only uses OEM connectors designed for the application. The 2 Pin alternator connector is an OEM Bosch connector and not a cut-down Delphi connector.
