Adapters: H4 Non-Standard Pin-Out Swap (2x)

Manufacturer: Holley
Manufacturer part number: H820
$10.00

Unconventional: On rare occasion, the three-pin low and high beam connection from the wire harness on classic cars is wired in an unconventional format. The pin-out for low, high, and ground may be different than what is considered industry standard, or the positioning of those pins may be different. In any case, these adapter cables will allow you to connect the Holley RetroBright Headlights to your original wiring, without modification.
