There are VW vehicles with Quadlock II or Quadlock III main connectors for VW vehicles. Do I need to purchase an adapter?

AW: The set content of the Z-E2055 contains a main power harness with Quadlock II connector.

Vehicles featuring the newer Quadlock III connector – also see the compatibility list extension of the Z-E2055 for Quadlock III cars – require the item Z-E2050-QL3 for the connection of device in the vehicle. The item N-ZE2050-QL3 is separately available from authorized ZENEC retailers.
