Description

If you don't feel comfortable cutting up your factory wiring or don't want to attempt to swap pins on your headlight plugs, Holley RetroBright adapters make it a plug-and-play affair. If the standard H4 male plug used on Holley RetroBright Headlights will not fit your female socket or you need to swap pins around to match up properly, these harnesses will make the job quick and easy.
