This adaptor plugs into the 13 pin towing electrics to allow the use of trailers or tow mounted accessories equipped with 12N/12S. Jaguar towing electrics are capable of powering caravans, trailers or lighting boards including those fitted with rear mounted LED lamp kits. However there is a minimum current required which some auxiliary lighting may not support. Please refer to the Owner's Handbook for details of the minimum and maximum electrical loading supported.
