Which towbar electrics do I need?

What are tow bar electrics?

Tow bar electrics (or tow bar wiring kits) are the power connectors between the vehicle and the mechanism the vehicle is towing, whether that be a trailer, cycle carrier or caravan. Tow bar electrics allow the indicators, fog lights, tail lights and brake lights on the back of your towing counterpart to function while driving, making it safer on the roads for you to tow.


What are my options?

Depending on what you are towing, you will either need single 7 pin (12N), twin 7 pin (12N & 12S) or single 13 pin electrics.

7 pin, twin pin and 13 pin electrics are available as universal wiring kits and for most modern vehicles, dedicated wiring kits are available.

Do I need dedicated or universal electrics?

We recommend dedicated electrics for any vehicle still under warranty as fitting universal wiring kits that do not specifically correspond with the vehicles electrical and wiring system will invalidate your manufacturer's warranty.

In most modern vehicles, a bypass relay s required when fitting universal kits to coordinate power between the vehicle and towing counterpart.
