MK5 Rabbit/GTI/Jetta Adapters to convert factory halogen 10 pin cars to 12 pin plugs for OEM HID "Xenon" lights. Each side comes with the proper terminated wire to run to the CECM (D/6 for Drivers side, A/5 for passenger side) for the high beam shutter if wanting to use that feature. No need to buy and splice in a VW repair wire like some other adapters. These are not for downgrading factory HID cars to 10 pin halogen ones.
