Holley Retrobright Pigtails, Adapters And Splitters

ADAPTERS: H4 NON-STANDARD PIN-OUT SWAP 

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.

SPLITTERS: QUAD LOW / QUAD HIGH HARNESS (H4M TO H4F/H4F)

Quad Hi-Low: In four-headlight systems it is common to have a dedicated low and high beam per side. With these splitters, You can now wire the system to work in parallel so that there are four low beams and four high beams.
