Shop caravan plugs and sockets at Truckstop Group
The 7-pin plug and socket has been the standard for towing electrics for decades, but the 13-pin configuration has become increasingly common on newer vehicles and caravans, since it carries additional circuits for reversing lights and, on some setups, a permanent 12V feed for the caravan's leisure battery.
A common problem when towing is a mismatch between an older 7-pin vehicle socket and a newer 13-pin caravan plug, or the reverse. Adaptors exist to bridge this gap, but they don't always carry every circuit across, so check what functions the adaptor supports rather than assuming full compatibility.
Poor connections at the plug and socket are a frequent cause of intermittent trailer lighting faults, often mistaken for a wiring problem further along the loom. Checking the pins for corrosion or damage is worth doing before assuming a more involved fault exists.
Frequently Asked Questions
What's the difference between a 7-pin and 13-pin caravan plug?
The 13-pin configuration carries additional circuits beyond the basic lighting functions covered by 7-pin, including reversing lights and, on many setups, a permanent 12V feed for the caravan's leisure battery.
Can I connect a 13-pin caravan to a 7-pin vehicle socket?
Yes, using an adaptor, though not every circuit will necessarily be carried across. Check what functions the specific adaptor supports before relying on it for anything beyond basic lighting.
Why do trailer lights fault intermittently?
A poor connection at the plug or socket, often from corrosion or a worn pin, is a common cause of intermittent lighting faults and is worth checking before assuming a more involved wiring problem.
How can I tell which plug or socket I need?
Check the pin configuration on both the towing vehicle and the trailer or caravan before ordering. If you're unsure, call our team and we can help confirm the right part.
