2023 Vauxhall Grandland Hybrid towbar installation. We have installed a Westfalia detachable towbar and 7pin trailer socket using Vauxhall dedicated and vehicle specific tow bar wiring. The final part of this tow bar installation is coding the Vauxhall’s ECU which tells the car when you are and are not towing. This gives the additional features like automatically cutting off rear parking sensors whilst towing.
