Hi i just bought a used Bailey pursuit caravan. The bloke that had it before myself obviously knew what he was doing as there are additional extension leads wired in , sky tv wires wired in alarm clocks wired in etc...i was hitching the caravan to my car yesterday when i noticed a small lead hanging down with a weather proof connection next to the jockey wheel. Does anyone know what this would be used for? or if it should be connected to something. I tried to look under the van but it was raining and i didnt fancy getting soaked. How do you add a photo and i'll stick a photo on.
