SUMMARY
Understanding the difference between 7 pin and 13 pin electrical connections for your towbar and which one you need.
Towbar Electrics: What You Need to Know
When having a towbar fitted, one of the key decisions is the electrical connection. This powers the lights on your trailer or caravan and, in some cases, provides additional functions.
7 Pin Electrics
The 7 pin socket provides the basic lighting functions needed for towing a trailer. It covers indicators, brake lights, tail lights, and fog lights.
13 Pin Electrics
The 13 pin socket is the European standard and provides all the functions of a 7 pin, plus additional features including a permanent power supply, charging for the caravan battery, and reversing lights.
Dedicated vs Universal
Dedicated electrics are vehicle-specific and work with your car's onboard computer. Universal electrics are a more affordable option but may not be compatible with all vehicle systems. We always recommend dedicated electrics for modern vehicles.
