You would be better putting one of these on the van rather than the adapter plug..........Alibaba said:We are taking delivery of a new car next month with fitted tow bar and 13 pin socket.
The caravan has two 7 pin plugs,however as we never use the 12S plug (grey) we will be using a 13 pin to 7 pin adapter for the 12N plug ,they only cost £4/£5 from most and take only seconds to fit.
