A CURT Quick Plug brake controller wiring adapter is one of the fastest and easiest ways to plug your brake controller into your vehicle. It requires no cutting or splicing! Just insert the vehicle-specific plug end into the OEM vehicle?s factory brake controller socket. The other end plugs into your CURT trailer brake controller. Quick Plug harnesses are available for a variety of vehicles and are unique for each vehicle application to provide the easiest possible installation. This particular brake controller harness fits certain years of the Volkswagen Atlas, Atlas Cross Sport and ID.4 with factory tow package (see application info to verify fitment).
