Wiring a 7-Way Round Pin European Trailer Connector
Updated 05/14/2025 | Published 07/25/2012
Question:
Where do I fit the large BROWN wire into the PLUG from the caravan? I have placed all the appropiate coloured wires into the appropiate plugs as descibed of 7 way round pin vehicle connector chart but now have the large BROWN wire left over. Can you please advise.

Expert Reply:
Usually a brown wire contains the running light circuit. However, you cannot go by wire color because it always varies from trailer to trailer. You will want to trace the wire back to where it leads on the trailer to determine its function and then make the connection in the trailer connector as needed.
If you have a European 7-Way then it will be a little different. I have included a picture that shows the typical functions of a European 7-Way.
