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.

Features:

  • Allows Holley RetroBright Headlights to connect to any non-standard H4 Sockets or those that require a pin swap
  • Eliminates the need to cut factory wiring
  • Can be used to replace old and brittle factory sockets

About Holley RetroBright

We all love the look of classic sealed beam headlights, but the dim halogen light output makes nighttime driving a potentially risky endeavor for you and your beloved classic. Holley's new RetroBright LED conversions offer a number of advantages over traditional sealed beam headlights such as better visibility, reduced power draw, no additional ballasts, and nearly 6 times longer life. Not only that, but because they are LED they take up less space, create far less heat, and use less power than other headlights.

The male plug (RBEC120) is also included and must be assembled once the proper pinout of the vehicle is determined. Simply slide the terminals in with the small pin facing inward and tug gently to ensure it has seated. If it pulls back out, use a small screwdriver or stiff metal object to push it outward just a fraction of an inch more until it seats in the male connector. See image 5.
