Holley Retrobright Adapter - H840
Many Toyota vehicles will have a switched ground that doesn't allow the RetroBright headlights to work right out of the box. This harness is designed to switch the ground back and then the RetroBright headlights can be plugged into this harness. We wanted to expand the great RetroBright experience to the switched-ground vehicles so more people can enjoy the safety and beauty of RetroBright LED lighting.
Allows Holley Retrobright Headlights To Connect To Most Toyota Vehicles With The Switched Ground; Designed So The Installation Is Easy And Effective; No Special Cutting Or Major Reconfiguration Of Factory Wiring
